Best Wild Swimming Spots in Cornwall
Written by UK Hidden Gems Editorial
Updated 5 August 2026
The best wild swimming spots in Cornwall are Trevone Natural Sea Pool, Mousehole Rock Pool, Polperro Chapel Pool, Chapel Rock Pool, Dozmary Pool, Portreath Rock Pool, Treyarnon Bay Tidal Pool and Porthtowan Tidal Pool.
Cornwall swims in the sea, and its finest wild swimming spots are the tidal pools cut and dammed into the rocks along its coasts, filling fresh with every high tide and sitting sheltered as the water drops. On the north coast, the natural pool at Trevone lies in the flat ledges near Padstow, and man-made pools hold seawater at Portreath, Treyarnon, Porthtowan and Perranporth's Chapel Rock.
In the south and west, Mousehole keeps its old children's bathing pool below the village near Penzance, and Polperro's Chapel Pool sits on a rocky shelf reached by cliff steps. Away from the sea entirely, Dozmary Pool spreads shallow and reed-fringed out on Bodmin Moor, tied in legend to King Arthur and Excalibur.
Most fill and empty with the tide, so timing around low water matters, and reaching them often means a scramble over wet, barnacle-covered rock. Here are eight wild swimming spots to seek out across Cornwall.
Trevone Natural Sea Pool

The Trevone Natural Sea Pool lies in the flat rock ledges at the western side of Trevone Bay, near Padstow. It is a tidal pool, filling and refreshing as the sea comes in and sitting exposed once the tide drops far enough for a swim.
Local swimmers know it as Tinker Bunny's Bathing Pool and keep an active community around it. It is a short walk along the coast path from the beach, over rocks that stay wet and slippery near low water.
Mousehole Rock Pool

Mousehole Rock Pool is a small tidal bathing pool on the shore of the Cornish fishing village of Mousehole, near Penzance, built long ago as a safe place for local children to swim. It is a shallow pool held by a low concrete wall against the rocks, filling and emptying with the tide, and it sits below the Rock Pool Cafe on the edge of the village.
From the water there are wide views across Mount's Bay toward St Michael's Mount and the Lizard. Reaching it means clambering over rocks, and there are no facilities at the pool itself.
Polperro Chapel Pool

Polperro Chapel Pool is a tidal bathing pool on the rocky shelf of Chapel Cliff, just west of the harbour at Polperro in Cornwall. It is filled and flushed by every high tide, and on a warm day the trapped water warms above the temperature of the sea.
Reaching it means walking up from the harbour onto the coast path and then down steep steps cut into the cliff to the rock ledge, so it is submerged at high tide and swimmable for a couple of hours either side of low water. There are no facilities, and the steps are steep and without handrails.

Chapel Rock Pool is a small tidal pool set into Chapel Rock, the large freestanding outcrop that stands on the sand at Perranporth in Cornwall. You cross the beach and scramble over a few rocks to reach it, dropping into water the sea refills on each tide.
Its long, narrow shape sits in a dip of the rock, shallow around the edges. It is a compact spot that fills quickly with people through the summer.
Dozmary Pool

Dozmary Pool is a small natural lake out on the open moor of Bodmin Moor, near Bolventor and the Jamaica Inn. Reed-fringed and shallow, it sits alone in a wide sweep of moorland, and has dried out completely in the worst droughts despite the old tale that it was bottomless.
It is tied in legend to King Arthur, said by some to be the lake where Excalibur was thrown, and to the ghost of Jan Tregeagle. Wading birds nest around its shores.
Portreath Rock Pool

Portreath Rock Pool is a man-made tidal bathing pool tucked in the rocks at the eastern end of the beach at Portreath, on the north coast of Cornwall, behind the harbour breakwater. It was cut and dammed into the rock, said to have been blasted out by local miners, to hold seawater as the tide falls, giving a sheltered place to swim below the cliffs.
It is usable only for a few hours either side of low tide and washes over at high water, reached by scrambling over the rocks. There are no facilities at the pool, though the village and its parking are close by.
Treyarnon Bay Tidal Pool

The Treyarnon Bay Tidal Pool is a rock pool set high on the rocks at the northern end of Treyarnon Bay, a sandy surf beach on the north Cornwall coast near Constantine Bay. Seawater refills the pool on every tide, and people use it for swimming and snorkelling, while the surrounding rock pools hold crabs, blennies and the odd sea hare.
Above the beach there is a pay car park, seasonal toilets and a cafe. Lifeguards cover the beach itself through the season.
Porthtowan Tidal Pool

Porthtowan Tidal Pool is a seawater bathing pool built into the rocks at the far end of the beach at Porthtowan, on the north coast of Cornwall. Large boulders were moved and a concrete dam built to hold the water back as the tide falls, giving a sheltered spot to swim away from the surf of the main beach.
It dates from around 1908, and reaching it means a scramble over barnacle-covered rocks, so it is usable only for a couple of hours either side of low tide and covers over when the sea comes back in. There are no facilities at the pool itself.
FAQs
When can you swim in Cornwall's tidal pools?
Cornwall's tidal pools are usable only for a couple of hours either side of low tide, since they fill and refresh at high water and then sit exposed as the sea drops, washing over again when it returns. Pools like Portreath, Porthtowan and Polperro's Chapel Pool cover completely at high tide, so timing around low water matters.
Which Cornwall wild swimming spot is best for families?
The Treyarnon Bay tidal pool sits above a sandy surf beach with a pay car park, seasonal toilets, a cafe and lifeguards on the beach through the season, and its surrounding rock pools hold crabs and blennies. Mousehole's shallow pool was built as a safe place for local children to swim.
What is Dozmary Pool on Bodmin Moor?
Dozmary Pool, out on the open moor of Bodmin Moor near Bolventor and the Jamaica Inn, is a shallow natural lake with no link to the tide. It is tied in legend to King Arthur, said by some to be where Excalibur was thrown, and reed-fringed with wading birds nesting around its shores.
Conclusion
Cornwall's wild swimming is mostly a matter of the tide. Along the north coast, seawater pools sit dammed into the rocks at Portreath, Porthtowan, Treyarnon and Perranporth's Chapel Rock, with the natural pool at Trevone in its flat ledges near Padstow.
In the south and west, Mousehole keeps its old children's bathing pool near Penzance and Polperro's Chapel Pool waits down its cliff steps. Out on Bodmin Moor, Dozmary Pool lies reed-fringed and legend-haunted, the one spot here that has nothing to do with the sea.
Most fill and empty with the tide and take a scramble over wet rock to reach, so check the times and tread carefully. These are the wild swimming spots to seek out across Cornwall.
