Cornwall is very nearly an island. Only about six miles separate the source of the River Tamar from the north coast, and everything beyond that line runs out into the sea, with the Atlantic to the north and west and the English Channel to the south. Along more than 400 miles of coastline sit high cliffs, hundreds of beaches, cove-sheltered fishing villages, wild moorland and surf towns. The sheltered south coast has been dubbed the Cornish Riviera; the north faces the open Atlantic. Thanks to that oceanic setting and the Gulf Stream, Cornwall has one of the mildest climates in the United Kingdom. Cornish people call it Kernow.
We at Travelmyth, the hotel search engine that ranks stays by your interests and needs across 60 stay categories, have put together this guide to what is worth your time in Cornwall. It opens with the two best-known names, the Eden Project and St Michael's Mount, then works west and north through the cliff theatre, the mining coast, the gardens, the ancient stones and the beaches, before signposting the towns and setting out the distances. Cornwall is long, so the order you visit things in matters. Read it start to finish, or jump to the section you came for.

Two clusters of domes sit at the bottom of a worked-out china clay pit outside St Austell, and the shock is the scale of the hole as much as what grows in it. The biomes are built from hundreds of hexagonal and pentagonal inflated plastic cells held on steel frames, and there are two of them: the larger recreates a rainforest, the smaller a Mediterranean climate. Inside the domes are tropical planting, an indoor waterfall and bamboo huts, and a viewing platform 50 metres up that lets you look down on the canopy. It is one of the largest indoor rainforests in the world. The planted areas run to some 35 acres, with a further outdoor section given to plants and wildlife native to Cornwall and the rest of the United Kingdom, while the Core building holds the science exhibitions and sculptures.
Eden was built as one of the UK Millennium Projects and runs as an educational charity and social enterprise, and is one of Cornwall's major visitor attractions; it passed 25 million cumulative visitors in February 2026. There is a zip wire across the site, a concert programme through the year and ice skating in winter at extra cost. Tickets can be booked in advance, which is worth doing in the school holidays.

The Mount is a tidal island in Mount's Bay, opposite the market town of Marazion, and the tide decides your visit rather than the other way round. A man-made causeway of granite setts links it to the shore and is passable between mid-tide and low water; when the sea covers it you cross by boat instead, and the boats operate seasonally, from 1 April to 31 October. The tidal range here reaches five metres. On the island, cobbled steps climb from the harbour village to the castle, with the subtropical garden laid out in terraces below it, designed in 1878 for the St Aubyn family. The harbour village still has a year-round population of about 30 people, and the fortified priory above has been home to the St Aubyn family since the mid-1600s; the Mount is run today by the National Trust and the family together.
Tradition holds that the site was regarded as sacred from the late fifth century, and it was briefly captured in Tudor times by Perkin Warbeck, the imposter who claimed to be one of Richard III's missing nephews. Two practical points: opening days and access vary by season, so check the current calendar before you travel, and wheelchairs and pushchairs cannot go up to the castle. Strong winds or rough seas can shut the island altogether, with 24 hours' notice where possible. The harbour and village are free to walk; the castle and gardens need a pre-booked ticket.

Tintagel sits on the north coast between Padstow and Bude, on a headland half severed from the mainland. The ruins you walk through belong to a castle built by Richard, 1st Earl of Cornwall in the 1230s, but the headland was an elite settlement long before that, and in the 12th century Geoffrey of Monmouth wrote that King Arthur was conceived here. A steel footbridge, opened to the public in August 2019, now carries visitors across the chasm to the island, and at low tide you can go down to the beach and into Merlin's Cave. It is a long way from anywhere else in this guide, so give it its own day: see the full Tintagel Castle guide.

The tiers are cut straight into the rock above Porthcurno, which makes the place look like something inherited from Rome. It is not. The theatre was begun in the early 1930s by Rowena Cade, working with her gardener Billy Rawlings and local labourers, and she was still at it into her eighties. It opened in 1932, and the first production it was built for was Shakespeare's The Tempest. The auditorium was dug out largely by hand, and the seats and the terraces are the result of decades of that labour; the names of the plays performed here are engraved into the seat rows. The cliff is south-facing and sheltered enough to carry a subtropical garden of succulents, palm trees and South African planting.
The theatre is open to visitors all year, with a varied performance programme running from around Easter to October and additional events in some school holidays; performances are often sold out and generally continue in wet weather unless conditions become unsafe, so book ahead if you want a seat rather than a look around. The name means "rocky place". If you are already on the beach below, the theatre is a ten-minute walk up the South West Coast Path.

Land's End is the most westerly point of mainland England, and it helps to know in advance exactly what that means on the ground. The headland itself is dramatic: rugged cliffs, the Longships Lighthouse offshore, and on a clear day the Isles of Scilly visible on the horizon. The land around the viewpoints is privately owned, and the site charges for parking and for individual attractions, among them the End to End Story and a 4D film experience, alongside the visitor centre, shops, restaurants and a small farm. The famous signpost is there, and photographs beneath it are charged for.
The Greeks knew this corner as Belerion, "place of the sun", and Diodorus Siculus wrote of its inhabitants as being made civilised by their dealings with foreign merchants. The best of it costs nothing: walk. Sennen Cove is about a mile away along the coast path, and the stretch south to Porthcurno is around six miles of rugged going, so allow two and a half to three hours. If you only stand in the car park and take the photo, you will wonder what the fuss is; if you walk twenty minutes in either direction, you will not.

Heligan is 200 acres of garden that stopped existing for most of a century. The estate's gardens were among the finest in England in the 19th century, then disappeared under brambles from the outbreak of the First World War, and it was the discovery of a tiny room buried under fallen masonry, and the inscriptions inside it, that crystallised the restoration. The house and outbuildings had been converted into flats in the 1970s and the garden was written off; it was rediscovered in 1990, and the rescue was carried out through the decade, including a televised project in 1996. The man behind it was Tim Smit, who went on to found the Eden Project, so two of the county's best-known attractions share an author.
What you walk through now is effectively an open-air museum of 19th-century horticulture, laid out in the Gardenesque style of separate areas with separate characters: kitchen gardens, a walled flower garden, an Italian Garden, and the Jungle, where a rope bridge crosses a small ravine. The Lost Valley has a 30-metre rope bridge and tropical planting. Two sculptures stand out: the Giant's Head just past the entrance, and the Mud Maid, a plant-and-rock sculpture. It is described as Europe's largest garden restoration project, and it takes longer than you think.

Kynance is on the west side of the Lizard peninsula, roughly two miles north of Lizard Point, and it looks the way it does because the rock is different: the dark green and red serpentinite of the Lizard, which forms the spectacular cliffs here. The National Trust describes it as a tidal beach for the adventurous, famous for that white sand, the turquoise water and the rock stacks. It is extremely busy with limited parking through July, August and September, and the beach itself comes and goes with the tide, so read the full Kynance Cove guide before you set off.

The sand at Porthcurno is not ordinary sand. It is seashell, pounded fine by the sea over a very long time, which is part of why the water above it reads so clear and turquoise. The beach sits below the Minack, 6.6 miles west of Penzance and 2.5 miles from Land's End, in a south-facing bay sheltered by high headlands. It also has an unlikely industrial history: the first submarine telegraph cable came ashore here in 1870, part of an early international link running to India. The sea is beautiful and genuinely dangerous, with strong currents and powerful waves. For tides, access and the telegraph story, see the full Porthcurno guide.

Lizard Point is the most southerly point of Great Britain, which makes it a different superlative from Land's End and worth the separate trip: the two are only 30 miles apart, and both are ends of the country in their own way. The Point is essentially a lighthouse with a small settlement behind it, plus the old lifeboat launch below. Park in the National Trust car park at Lizard village and walk the half mile down; there is a cafe at the bottom, seals are regularly seen offshore and dolphins occasionally. The peninsula is famous for its serpentine, a distinctive dark green metamorphic rock. Look out to sea and you are watching one of the busiest shipping lanes in the world, on the westerly approach to the English Channel. Two pubs in Lizard village both claim to be the southernmost in the United Kingdom, which is a dispute nobody seems keen to settle.

Sennen Cove is a small coastal village sitting just above a long white beach, and it is the beach that draws people: Whitesand Bay has a reliable surf break year-round. There are surf schools here, as there are at Newquay, Bude, Hayle and St Ives. Three car parks serve the village, and the third of them sits on top of a steep cliff, which is worth knowing before you commit. The coast path is the reason to linger: it is about 25 minutes round to Land's End, and the full walk from Sennen Cove to Porthcurno by way of Land's End runs to roughly 10 kilometres.

Fistral is Newquay's main draw, a wide beach with some of the best surf in the country, and it has been called the surf capital of England. Newquay is one of Cornwall's largest towns, and it sits on the north coast, with Watergate Bay as its other big sand. The whole north coast from Bude down to Land's End picks up consistent Atlantic swell, which is what makes Cornwall the centre of British surfing. If you have never stood on a board, this is a great place to learn: numerous surf shops around Fistral hire boards and run lessons, and RNLI lifeguards patrol daily from 3 April to 1 November, 10am to 6pm. The competitive calendar clusters here too, with national-level surfing competitions through the year and the Boardmasters festival in August. Newquay's harbour, tucked round the corner, is still a working one.

A short drive north of Newquay, a line of huge rock stacks rises straight out of the sand below the cliffs. Read the access position before you go, because it has changed: there is no access to the beach at Bedruthan following a rock fall in 2019, and the site is named Carnewas and Bedruthan Steps. The clifftop is still open and the headland trail still gives you the view, which is the reason most people come. Even when the beach was open it was not a swimming beach: the currents are strong, there is no lifeguard, and at high tide half the sand disappears and some of the stacks are cut off entirely. Treat it as a walk with a view rather than a day on the sand. The Padstow to Bedruthan Steps stretch is rated among the finest walking in Cornwall.

Lanhydrock sits outside Bodmin in about four square kilometres of parkland, and it gives a full picture of how a large Victorian household actually ran, upstairs and downstairs both. Parts of the house are Jacobean, but most of what you see was rebuilt after a fire in 1881: the chapel, the gatehouse, the two-storey porch and the north range with its 116-foot long gallery survived, and the gallery's ceiling is a masterpiece of Jacobean plasterwork. It was the summer house of the Agar-Robartes family until the National Trust took it on in 1953. Film crews have used it too, including the 1996 adaptation of Twelfth Night with Helena Bonham Carter, Toby Stephens and Ben Kingsley. The gardens are extensive and well kept, and much of the visit is indoors.

Henry VIII built these two as a pair, one on each side of the mouth of the River Fal, to protect the estuary from foreign invasion. Pendennis went up between 1539 and 1545 on a rocky headland high above Falmouth, one of a handful of distinctive circular artillery forts built in the 1540s, and Tudor, Napoleonic, Victorian and 20th-century guns have all been placed there since; it was crucial in the Civil War, and the site now carries an interactive discovery centre, a Tudor gun room and a wartime cartoon collection, with activities covering the soldiers stationed in Falmouth in the First World War.
St Mawes, on the Roseland Peninsula opposite, is a four-storey artillery fort from the same programme and the same decade. It is a good deal smaller than Pendennis and in some ways better: one of the best preserved forts on the English coastline, changed very little over the centuries, with Latin inscriptions dedicated to Henry and Edward VI and a long view over Carrick Roads. Do both in a day if you can; the water between them is the point.

Inland Cornwall gets skipped, and Bodmin Moor is what people are skipping: a granite upland of tors, Bronze Age burial chambers and stone circles that can feel empty even in peak season. It holds the highest land in the county. Brown Willy is the summit at 420 metres, or 1,378 feet, and its name comes from the Cornish Bronn Wennili, "hill of the swallows"; Rough Tor stands right beside it as the second highest. A good concentration of prehistory sits around Minions, on the south-east edge, where several circular walks link the sites. The Hurlers are three Bronze Age stone circles, and local legend says the stones are men petrified for playing hurling on a Sunday.
The Cheesewring nearby is a stack of granite slabs left by weathering, balanced improbably enough that giants have been blamed. Jamaica Inn sits in the middle of the moor, a former coaching house long associated by tradition with smuggling; Daphne du Maurier came across it after getting lost up here and later wrote the novel that carries its name. In 1983 the police took a report of a "wild beast" haunting the moor, which tells you something about the atmosphere.

The stretch of cliff around St Just and Pendeen is where Cornwall's mining past is still written into the landscape, and the derelict engine houses along it are a World Heritage Site. Geevor at Pendeen is the key centre within the Cornish Mining World Heritage Site and the one to visit if you only do one: you can go underground and then walk the processing plants above ground, and the best room is The Dry, the miners' old offices and changing area, left as it was in the early 1990s. Geevor closed as a commercial tin mine in 1986, with limited activity continuing on the site afterwards. Levant, further along the same coast, keeps a restored clifftop engine house with a working beam engine, the only Cornish beam engine anywhere in the world still in steam on its original mine site; it runs by pre-booked tour and is National Trust.
At Botallack the Crowns engine houses stand on the cliffs above the sea, and the workings run half a mile out under it; around 20,000 tonnes of copper are thought to have come out of the mine, which closed in 1895 when copper and tin prices fell. Wheal Coates, further up the north coast near St Agnes, opened in 1802 and worked until 1889, and its engine house above the sea is one of Cornwall's most iconic sights. These landscapes were inscribed on the UNESCO list in 2006.

St Ives drew painters and sculptors in the 20th century for its quality of light, and the town has kept the argument going ever since. Ben Nicholson moved here with his then wife, the sculptor Barbara Hepworth, at the outbreak of the Second World War; Mark Rothko was among the artists who came. Tate St Ives, built in the 1990s around a former gasworks, is a branch of the London gallery, set on the cliff with a circular rotunda and a wide view over the town, the harbour and Porthmeor Beach. It shows British work of the twentieth century alongside a changing exhibition programme. Nearby, the Barbara Hepworth Museum and Sculpture Garden occupies the artist's own sea-view home and studio; it is run by the Tate and holds the largest group of Hepworth's works, permanently on display in the place in which they were created. Do the two together, then walk down to Porthmeor, which is a five-minute walk from the centre of town.

Cornwall’s mild maritime climate is why the south coast is garden country. Trebah is a subtropical garden running down a steep ravine to its own beach, planted with giant gunneras, rare rhododendrons and towering bamboo, and holding several Champion Trees, the largest of their species in the country. It is the product of 160 years of continuous making. The beach at the bottom has a long view over the Helford River to Falmouth Bay, and it also has a war memorial: this was the departure point for the 29th US Infantry Division on its way to Omaha Beach. The garden charges entry, but the beach can be reached free by a public footpath. Across the Fal, Trelissick is a National Trust house and garden on a headland at the river mouth, full of magnolias, camellias and rhododendrons, with an Iron Age promontory fort and an 18th-century quay on the estate.

Falmouth has the third deepest natural harbour in the world, and it has long been a start and finish line for round-the-world sailors, so a maritime museum here is not decoration. The National Maritime Museum Cornwall sits on Discovery Quay, with five floors of boats, one of them below the waterline. It covers Cornwall's maritime heritage and holds a large collection of boat models, with displays on lifeboats and ocean survival, shipwrights work in an open boat-building workshop, and there is a lookout tower with a view across the harbour, the docks and the estuary. Children can sail remote-controlled models. Falmouth Art Gallery is in the same town.

Bodmin Jail dates to the late 18th century and is built from Delank granite, which gives it a bulk you feel from the street. It was ahead of its time, with exercise areas, separate male and female accommodation and provision for prisoners' healthcare. The visit is now an immersive one, with the Dark Walk, a cinematic journey through Cornwall's history and its prisoners' stories, and a reconstruction of life as an 18th-century prisoner. Up on the north coast at Boscastle, a fishing village set in a narrow valley where the rivers Jordan and Valency meet, the Museum of Witchcraft and Magic covers the witch trials, alchemy, ceremonial magic, Freemasonry and Wicca. It was opened in 1960 by Cecil Williamson and now holds more than 3,000 objects and over 7,000 books. Boscastle's harbour is worth the stop by itself: the entrance winds round several bends, so the water is hidden until you are almost in it.

Cornwall carries Bronze Age stone circles and Iron Age villages in unusual numbers. Chysauster, near Penzance, is the ruin of a late Iron Age and Romano-British settlement now run by English Heritage, thought to have been lived in from about 100 BC to the third century by the Dumnonii; it holds the remains of around ten houses, in a form found only in far west Cornwall and the Isles of Scilly, and it is one of the best preserved sites of its kind in Britain. The Merry Maidens, close to Lamorna, is a circle of 19 regularly spaced Bronze Age megaliths at least 3,500 years old; a Victorian-era legend explains them as local girls turned to stone for breaking the Sabbath. Mên-an-Tol is three upright granite stones, the middle one holed and 1.3 metres across, believed to date to the early Bronze Age; local tradition says a woman who passes through it seven times backwards at full moon will conceive, and the alternative name, the Crick Stone, comes from a belief that nine passes cured a child of rickets.
On the southern edge of Bodmin Moor, Trethevy Quoit is a Neolithic burial chamber of 3500 to 2500 BC, five standing stones under a capstone of about 20 tonnes, over nine feet high and known locally as the Giant's Tomb. It predates the great pyramids of Giza and belongs to Britain's Neolithic period, before metalworking became established here.

Two woodland waterfalls, one on each side of the county. St Nectan's Glen lies between Tintagel and Boscastle, a 15-minute drive from Tintagel Castle, and the walk in follows the River Trevillet, which reaches the sea at Rocky Valley. Three waterfalls are reached along a woodland boardwalk; the main one, St Nectan's Kieve, falls 18 metres through circular rock formations, which is why it is also known as the Pothole Waterfall. At the top of the falls are the ruins of a hermitage traditionally associated with St Nectan, a reputed early Christian holy man. Golitha Falls, on Bodmin Moor, is a different mood: a series of cascades where the River Fowey runs through a steep gorge in ancient oak woodland, with footpaths along the riverside. The Woodland Trust rates it as suitable for children, there are places to paddle, and you might spot otters and kingfishers.

Cape Cornwall was long believed to be the most westerly point in Cornwall, until better surveying showed that Land's End lies further west. It is a short walk from the car park to the tip, with a chimney stack from the old Cape Cornwall mine standing on the crown of the headland as a monument to the district's mining, and a National Coastwatch lookout hut you can visit. At the other end of the north coast, Godrevy Point marks the northern limit of St Ives Bay, and just offshore stands Godrevy Lighthouse, a white 26-metre octagonal tower on its own small island. It is generally taken to be the lighthouse of Virginia Woolf's To the Lighthouse. Seals haul out on the rocks at Godrevy Head, and the beach running from Godrevy through Gwithian to Hayle is three miles long. Note that Godrevy beach has a seasonal dog ban in July and August between 10am and 6pm.

The South West Coast Path, at 630 miles, is the longest established National Trail in the country, and its Cornish stretch runs from Bude in the north round to Saltash near Plymouth on the south coast. It is not a circular route, so you need transport back to the car, and the stages are rarely long but often strenuous, because the path drops to sea level and climbs out again at every valley. Good half-day sections to start with: Tintagel Castle to Boscastle, 8.7 kilometres of north-coast cliff; St Ives to Zennor, six miles past hidden coves; and Looe to Polperro, an easier five miles on the south coast. On any given stretch, it is one of the best things in this guide.

The Scillies lie about 45 kilometres off the western tip of Cornwall, and they reward more than a day, though day trips run by both sea and air: ferry from Penzance Harbour, or fly from Land's End, Newquay or Exeter into St Mary's Airport. In the summer season the ferry runs at least once a day from Penzance to Hugh Town on St Mary's, the largest island and home to the Isles of Scilly Museum. The climate is a category of its own: the islands average fewer than two days of air frost a year. If you can time it, the world pilot gig rowing championships are held here every year.

Newquay Zoo keeps lions, monkeys and penguins among many other species, takes part in conservation breeding programmes for threatened species and has been repeatedly recognised for sustainable tourism; there is an Oriental Garden of Japanese and Asian planting inside the grounds. The Cornish Seal Sanctuary at Gweek, set on the Helford Estuary, has been rescuing and rehabilitating seals since 1958, taking in grey seal pups each season alongside resident seals, penguins, sea lions and otters, with feeding sessions and talks through the day.
Lappa Valley, a short drive from Newquay at St Newlyn East, runs a narrow-gauge steam railway along an old mineral line, with a boating lake, adventure golf, soft play and play areas. And the telegraph museum at Porthcurno is a better children's museum than it sounds: by the 1920s, Porthcurno had become the largest telegraph station in the world, and you can walk into the underground wartime bunker and see the cable hut where the lines came ashore.
Rain is part of the deal, and Cornwall has plenty of indoor options for it. The Eden Project is the obvious answer, since the whole point of the biomes is that the weather is on the inside. Carnglaze Caverns at St Neot, on the edge of Bodmin Moor, is a former slate mine where the tour runs about 60 metres underground at a constant 10C and finishes at an underground lake of clear blue-green water, in over six acres of woodland and valley. Geevor gives you a mine and a museum in one; the National Maritime Museum Cornwall gives you five floors; Tate St Ives and the Barbara Hepworth Museum are both in the town and easily combined. Bodmin Jail and the Museum of Witchcraft and Magic are both indoor and both improved by bad weather. Lanhydrock is a National Trust house with upstairs and downstairs rooms to walk through.

The coast path costs nothing and dominates walking in the county, which takes care of most days. Beyond it: Boscastle village and harbour belong to the National Trust and can be walked free of charge. The harbour and village on St Michael's Mount are free to visit, and it is only the castle and gardens that need a ticket. Trebah charges for the garden, but its beach is reachable by a public footpath at no cost. Falmouth Art Gallery has no entry charge, and Truro Cathedral, completed in 1910, asks only for a donation. Lusty Glaze near Newquay is privately owned but free to visit, and the Flicka Foundation donkey sanctuary outside Falmouth, home to more than 100 rescued donkeys, is free to look round. If you plan to visit several National Trust properties in a week, an Explorer Pass comes in 4, 8 and 14-day versions; National Trust membership also lets you park free at their sites, which is often the real saving.

Each of these deserves its own guide, so treat this as a map rather than a list. St Ives is the county's art town, home to the Tate and the Hepworth museum; it is one of the most popular places in Cornwall and very busy in summer, so park at St Erth and take the train in. Newquay is the surf town and one of Cornwall's largest. Penzance is as far west as the national rail network reaches. Falmouth has the deep harbour, the maritime museum and the art gallery. Truro is Cornwall's only city, with a Gothic Revival cathedral finished in 1910. Padstow, ten miles north of Newquay, is the county's best-known food town.
Bude sits on the Devon border and has several beaches and its famous sea pool. Looe is split into East and West by its river, five coastal miles from Polperro, where the streets are too narrow for cars. Port Isaac is where Doc Martin was filmed and the inspiration for the film Fisherman's Friends; most parking is at the top of the hill. Fowey was Daphne du Maurier's home for more than half her life and has a foot ferry to Polruan. Mousehole was burned by Spanish raiders in 1595, so all but one of its buildings post-date that.
Charlestown is a Georgian port with tall ships in the harbour, and part of the Cornwall and West Devon Mining Landscape World Heritage Site. Mevagissey was the centre of the pilchard trade and sits close to Heligan. Marazion is the gateway to St Michael's Mount. St Mawes faces Falmouth across the water from the Roseland. Cadgwith is thatched cottages tumbling to a working cove, and Zennor, where Cornish was still spoken in the late 18th century, has a mermaid carved in its church.

This is the section that changes your itinerary. Cornwall is long: the coastal route from the Devon border west of Plymouth, going by St Austell, Falmouth, Land's End, St Ives and Bude, runs about 200 miles. London to central Cornwall is roughly 250 miles, with driving times commonly around five hours or more depending on destination and traffic, and the motorway ends before you arrive, so the last stretch is slower winding road. Two roads carry most traffic: the A30, which leaves the M5 at Exeter, enters at Launceston, crosses Bodmin Moor and passes Bodmin before branching to St Austell, Newquay and Truro, and the A38.
On the north coast the A39, the Atlantic Highway, serves Bude, Wadebridge and Padstow before running on to Truro and Falmouth; further south the road from Falmouth to Penzance runs through Helston, where the A3083 drops to Lizard Point. Away from these, lanes are frequently single-vehicle width, and meeting a car means one of you reverses to a passing place. In peak season, allow substantial extra time between major towns. By rail, Great Western trains from London take four to five hours, and the Night Riviera sleeper runs from Paddington to Penzance every night except Saturdays in about eight hours; Penzance, St Ives, Newquay, Truro and Bodmin Parkway all have stations.
Trains link the main towns well, but public transport becomes much thinner away from them, and taxis can require advance booking. Two more practicalities: many Cornwall Council car parks went cashless on 1 August 2026, with card, contactless and mobile payment now the norm and cash kept at selected sites, and there are two high tides and two low tides a day, changing roughly every six hours, which matters at St Michael's Mount, Kynance and Porthcurno.
When to go. The main visitor season runs roughly from late spring through September. July and August are the warmest months, with August marginally the warmer of the two and a sea temperature around 17C, while the longest days come around the June solstice. Cornwall enjoys a relatively mild maritime climate, and the wind off the Atlantic keeps the coast from getting too hot. The sweet spots are the second half of May, the first half of June and September, which skip the August road times. The quietest stretch is generally reckoned to be November to March, and in especially mild winters, early spring flowers can appear remarkably early.
How long you need. Distance, not opening hours, sets the pace here. This guide groups the county roughly into three: a western end taking in Penzance, St Michael's Mount, the Minack, Porthcurno, Land's End and the Tin Coast; a northern one taking in Tintagel, Boscastle, Padstow and the Bedruthan cliffs; and a southern one taking in Falmouth, the Fal castles, the Helford gardens, Heligan and the Eden Project. We would give a long weekend to one of those groups, five days to two of them, and a week if you also want the Lizard and Bodmin Moor without spending your holiday in the car, because Land's End and Lizard Point alone are 30 miles apart on small roads.
Where to stay. The choice that matters is which coast. The north is where the long sandy beaches and the Atlantic swell are; the south, the Cornish Riviera, is more sheltered, with the broad estuaries and the gardens. Base yourself in the half of the county your list leans towards rather than trying to hold the middle. If you would rather not drive, Penzance, St Ives, Truro and Newquay are all on the rail network, while Bodmin is served by nearby Bodmin Parkway. Travelmyth, the search engine that filters stays across 60 categories, lists stays across Cornwall ranked by the things you actually care about, so you can sort by what your trip needs rather than scrolling past what it does not.
