Best Wild Swimming Spots in the UK — 15 Places to Take the Plunge

River pools, tarns, tidal coves and lidos — the UK's most beautiful wild swimming spots, with honest notes on access, safety and when to go.

Best Wild Swimming Spots in the UK — 15 Places to Take the Plunge

Wild swimming has gone from niche to national obsession, and Britain is quietly brilliant for it — hidden river pools, mountain tarns and tidal coves, most of them free. Here are 15 of the best, with the honest safety bits included.

Rivers & pools

  • Sharrah Pool, River Dart (Devon) — a deep, clear Dartmoor pool that's the classic English river swim.
  • Gaddings Dam (West Yorkshire) — a moorland reservoir with a genuine sandy beach, high above Todmorden.

Mountains & tarns

  • Llyn Gwynant (Snowdonia) — a jaw-dropping lake beneath the peaks; cold and deep, so respect it.
  • Lake District tarns — Blea Tarn and Angle Tarn reward the walk in with solitude.

Coast & islands

  • The Fairy Pools, Isle of Skye — turquoise plunge pools under the Cuillin; busy but unforgettable.
  • Hampstead Heath Ponds (London) — the capital's beloved lifeguarded swim, open year-round.

Safety, honestly

Cold water is the real risk — enter slowly, never jump into water you haven't checked, and get out while you still feel warm. Rivers rise fast after rain, so skip fast or brown water. Water shoes and a bright tow float make everything safer.
