Why Devon's Rivers Are Worth the Walk

Devon has more river mileage than almost any other English county, and much of it runs through deep wooded valleys that keep the water cool, clear and fringed with mossy boulders. The good spots are rarely next to a car park. Expect a thirty-minute walk, a steep descent, and the reward of a plunge pool the colour of weak tea — the tint comes from peat, not dirt, and it's harmless.

Most of the best swimming lies on Dartmoor's fringes, where granite bedrock forms natural pools and small waterfalls. Water here is soft and often astonishingly clean, but it is also cold, fast after rain, and unpatrolled. There are no lifeguards, no signs telling you it's safe, and no one to call if you get into trouble. Treat every swim as your own responsibility.

Classic Spots on the Dart, Teign and Tavy

Devon's rivers each have a different character, and knowing which suits your ability matters more than chasing a famous name.

• Sharrah Pool, River Dart — a long, deep granite pool in Holne Chase, reached by a forty-minute walk from the Newbridge area. Genuinely cold, genuinely stunning, and busy on sunny weekends.
• Spitchwick and Deeper Marsh, near Poundsgate — the classic Dart dip, with shallow gravel shelves for cautious swimmers and deeper water upstream. Popular with families, so go early or late.
• Fingle Gorge, River Teign — pools beneath the wooded slopes near Fingle Bridge. Beautiful, but the gorge funnels water quickly after rain.
• The Teign at Steps Bridge and Dunsford — gentler, shallower and easier to access, good for a first river swim.
• The Okement at Okehampton — quieter pools on the northern moor, often overlooked.

If you prefer salt water, Devon also has tidal pools at Shoalstone near Brixham and in the rocks around Ilfracombe, which fill and empty with the tide and offer a safer introduction to cold water.

Reading the Water Before You Get In

River conditions change within hours. A storm ten miles upstream can turn a lazy pool into a brown torrent before the rain reaches you. Check the forecast for the whole catchment, not just your location, and never swim after heavy rain — wait at least forty-eight hours for levels to drop and clarity to return.

Look for these warning signs and walk away if you see them:

• Fast, discoloured or foaming water, or debris floating past.
• Weirs, sluices and leats — their recirculating currents can hold even strong swimmers under.
• Submerged trees and branches, which trap swimmers in moving water.
• Steep, slippery entry points where a fall could cause injury before you're even in the water.

Enter gradually, feet first, and never dive into opaque water. If you're caught in a current, float on your back with feet downstream and steer towards the bank rather than fighting it.

Cold Water, Temperature and Sensible Swim Times

Devon rivers sit around 4–7°C in winter and reach perhaps 16–18°C at the height of summer, which is still bracing. Cold water shock causes involuntary gasping and a racing heart in the first thirty seconds, so keep your head above water, breathe slowly and let your body settle before swimming properly.

As a rough guide, a beginner in summer water should aim for five to ten minutes; in winter, two to three minutes is plenty. Get out while you still feel fine — the afterdrop hits as you warm up. Dress quickly in layers, add a hat, and have a warm drink waiting. Swim with someone else, use a brightly coloured tow float so boats and other river users can see you, and tell a friend where you'll be, as mobile signal is patchy in most valleys.

Access, Parking and Local Manners

Many of Devon's pools sit on private land with long-standing permissive access. That access survives only while swimmers behave. Use marked footpaths, leave gates as you find them, keep dogs under control around livestock, and never block a farm gateway or passing place — narrow Devon lanes are working roads.

Where parking charges apply at places like Fingle Bridge, pay them; the money maintains the tracks and toilets everyone uses. Carry cash or a card, arrive early in summer, and be prepared to walk further if the nearest car park is full. Wild camping is not permitted on most of Dartmoor without landowner permission, so plan your swim as a day trip.

Leaving No Trace — and Why It Matters Here

Devon's rivers are among the last strongholds of Atlantic salmon and sea trout, and their spawning gravels are fragile. Building dams, moving stones and trampling redds (spawning beds) in autumn and winter causes real harm. Leave the riverbed alone.

Take all litter home, including fruit peel and wet wipes. Don't light fires or disposable barbecues on riverbanks. Wash with plain water only — soap, shampoo and sunscreen residues pollute the water you came to enjoy. Go to the toilet well away from the water, at least thirty metres from the bank and buried if possible. Do all this, and these pools will still be worth swimming in for the next generation.
