Wild Swimming in the South West: Best Spots in Devon and Cornwall
If you’ve ever stood at the edge of a river on a warm August afternoon, looked at the water, and thought “I absolutely should get in that” — welcome. You’re one of us. Wild swimming in Devon and Cornwall is, quite simply, some of the finest open water swimming available anywhere in England, and arguably anywhere in the UK. The South West has a combination of ingredients that most regions can only dream about: granite sea cliffs, Atlantic-fed rivers, ancient wooded valleys, tidal coves, and — on a good day — water temperatures that won’t completely rearrange your organs.
This guide is written for swimmers who actually want to get in the water, not just photograph it. Whether you’re a seasoned cold water swimmer who greets January with a thermos and a grin, or someone who’s only just discovered that swimming outdoors is an option, you’ll find something here worth planning a trip around.
Why Devon and Cornwall?
The South West Peninsula juts out into the Atlantic further than any other part of England, which does two significant things for wild swimmers. First, it gives you an extraordinary coastline — over 630 miles of it in Cornwall alone if you follow every headland and inlet. Second, it keeps the climate noticeably milder than the rest of the country. Sea temperatures along the Cornish coast rarely drop below 9°C even in the depths of winter, which is cold, but not the bone-jarring shock you’d get off the Yorkshire coast in February.
Then there are the rivers. Dartmoor in Devon and Bodmin Moor in Cornwall act as giant sponges, collecting rainfall and releasing it through dozens of rivers and streams that carve their way through ancient granite landscapes. These moorland rivers are clean, fast-moving, and often utterly beautiful. The Dart, the Teign, the Tamar, the Fowey — these are rivers with character, and they reward the swimmer who takes the time to know them.
Wild Swimming on the Coast
Kynance Cove, the Lizard Peninsula, Cornwall
There are photographs of Kynance Cove that look so improbable — turquoise water, serpentine rock formations, white sand — that people assume they’ve been heavily edited. They haven’t. Kynance is the real thing. Owned and managed by the National Trust, it sits on the western side of the Lizard Peninsula, which is the southernmost point of mainland Britain.
Swimming here is best done around low tide, when the coves and channels between the rock stacks open up and create genuinely extraordinary swimming conditions. The water clarity is exceptional. At high tide, some of the lower areas flood, so always check the tide tables before you go — the National Trust website carries specific advice for Kynance, and the car park fills fast in summer so arrive early.
The serpentine rock — a dark green, almost otherworldly stone — is unique to the Lizard, and it makes the sea here look an almost Caribbean shade of blue when the sun is out. Water temperatures in July and August typically hover between 16°C and 18°C, which is perfectly swimable for most people without a wetsuit, though a wetsuit will always extend your time in the water.
Bedruthan Steps, North Cornwall
The sea stacks at Bedruthan are iconic, and on a big swell they’re genuinely dramatic. However, swimming directly at Bedruthan is not recommended — the beach has no lifeguard cover, access requires a steep descent, and the surf and currents here can be fierce. This is one to visit for the view rather than the swim.
That said, Mawgan Porth, just a few miles south, is an excellent alternative with a wide sandy beach, easier access, and calmer conditions in the right weather. The RNLI cover beaches further down the coast, and knowing which beaches have lifeguard cover is part of responsible planning in North Cornwall, where the Atlantic swells can be deceptive.
Porthcurno Beach and the Logan Rock, West Cornwall
Porthcurno sits in a narrow valley between two headlands near Land’s End, and the combination of white quartz sand and clear Atlantic water is genuinely stunning. The beach faces south, which gives it some shelter from the prevailing south-westerly winds, and on calm summer days the swimming is superb.
The Minack Theatre sits on the cliffs directly above, which means if you time your swim for an evening performance, you can watch the theatre from the water — one of the more memorable experiences available in British open water swimming. The water here gets good summer temperatures and the beach is sandy underfoot, making entry and exit straightforward.
Broadsands Beach, Torbay, Devon
Torbay markets itself as the English Riviera, and while that comparison has its limits, there’s a genuine case to be made that this stretch of South Devon coastline offers some of the warmest and most protected sea swimming in England. Broadsands, on the southern edge of Torbay, is sheltered, sandy, and receives RNLI lifeguard cover during the summer season.
The bay’s south-facing aspect means it accumulates warmth through the summer months, and by August the water is often genuinely warm by British standards — 18°C to 20°C is not unusual. For families or newer swimmers who want a gentle introduction to sea swimming, Broadsands is an excellent starting point. The town of Paignton is nearby with all the amenities you’d expect.
Cawsand and Kingsand, Plymouth Sound
These twin villages on the Rame Peninsula across Plymouth Sound from the city are something of a hidden gem. They sit in a sheltered bay that’s partly protected by the Plymouth Breakwater, which takes the edge off Atlantic swell and makes for reliably calm conditions. The villages themselves are genuinely charming — narrow lanes, pastel-painted houses, a handful of decent pubs — and the swimming is excellent.
Access is either by ferry from Plymouth’s Barbican (a wonderful way to arrive) or by car via the Rame Peninsula. The beach shelves gently, the water is clear, and on summer weekends a lively mix of locals and visitors make the most of conditions that, on a good day, feel more Mediterranean than Cornish.
River Swimming in Devon and Cornwall
Dartmoor: The River Dart
The Dart is arguably the finest wild swimming river in England. It rises on the high moor above Two Bridges, drops through ancient oak woodland, and arrives at the sea at Dartmouth having passed through some of the most varied and spectacular landscape in the South West. For wild swimmers, the section between Dartmeet and Holne is particularly celebrated.
Spitchwick Common, near Poundsgate, is the most popular wild swimming spot on the Dart — and for good reason. A broad, shallow stretch of river opens into deeper pools, there are natural jumping rocks (exercise serious caution and always check depth before jumping anywhere), and the surrounding moorland is spectacular. It can get genuinely busy on summer weekends; arrive by 9am or visit mid-week if you want space.
The Dart at Dartmeet, where the East and West Dart converge, offers a different experience — more remote, more rugged, and surrounded by open moorland. The water here is peat-stained, that characteristic dark amber colour of moorland rivers, and it runs fast after rain. Always check river levels before swimming in the Dart — it can rise quickly after heavy rainfall on the moor, and the current in the narrow gorge sections should not be underestimated.
The River Teign, Devon
The Teign runs along the northern edge of Dartmoor before turning south to reach the sea at Teignmouth. The upper river, particularly around Fingle Bridge and through the Teign Gorge, is outstanding for swimming. The gorge itself is part of the Castle Drogo estate, managed by the National Trust, and the combination of ancient woodland, rock formations, and clear moorland water is hard to match.
Fingle Bridge is a medieval stone bridge and a popular starting point for walks into the gorge, and there are several excellent swimming pools accessible along the riverbank. The Angler’s Rest pub at Fingle Bridge is a welcome sight after a cold swim. The Teign runs cooler than many lowland rivers because of its moorland source, so even in high summer you can expect temperatures in the 14°C to 16°C range — refreshing rather than warm.
The River Fowey, Cornwall
The Fowey (pronounced “Foy”) rises on Bodmin Moor and flows south to the estuary at the town of Fowey. The upper sections of the river around Golitha Falls are particularly special — an ancient oak woodland through which the river tumbles over granite boulders in a series of waterfalls and deep pools. It’s a Site of Special Scientific Interest (SSSI) and managed in part by Natural England.
Swimming at Golitha Falls requires some care — the rocks are slippery, some of the pools are deeper than they appear, and the falls themselves should not be swum near. But the pools below the falls offer genuinely lovely swimming in an ancient, atmospheric setting. The car park at Golitha Falls is well signposted from the B3360 near Liskeard.
The River Avon (Dartmoor), Devon
Not to be confused with its more famous namesake elsewhere in England, the Dartmoor Avon is a quieter, less visited alternative to the Dart that rewards those willing to do a little more legwork. The section below Avon Dam reservoir, through Shipley Bridge, offers excellent moorland swimming with far fewer crowds than Spitchwick. The water is clean, the scenery is open moorland at its best, and on a weekday in July you may well have it entirely to yourself.
Moving Forward
Once you have the fundamentals in place, the possibilities open up considerably. The UK offers fantastic opportunities for anyone interested in this hobby, and with the right foundation you will be well placed to make the most of them.
