Short answer: You want firm, flat sand on a falling tide, shelter from the prevailing south-westerly, and space away from the main beach access. Gyllyngvase in Falmouth and Porthminster in St Ives are the most sheltered; Perranporth and Watergate have the most space. Go early — before 8am the beach is yours.
Cornwall looks made for beach yoga and mostly isn't. Soft dry sand won't hold a pose, the wind picks up by mid-morning, and the popular beaches are too busy to relax on. But get the beach, the tide and the hour right and it's genuinely one of the better places in Britain to practise outdoors.
South-east facing on a sheltered bay, which makes it calm when the north coast is unusable. Flat, walkable from town, with a café and proper facilities right there. If wind is your main worry, this is the pick.
Faces east-south-east, so it's sheltered exactly when Porthmeor round the corner is being battered by a westerly. Gently sloping with a wide expanse of firm sand at low tide, and genuinely lovely light in the morning.
Three miles of beach means you will always find somewhere to yourself, even in August. Walk north away from the village and it empties out completely. Exposed to the wind, so this is one for a still morning — and the dunes give shelter if it gets up.
Two miles of beach with a huge flat expanse at low tide. Popular with surfers, but the beach is big enough that this doesn't matter. Facilities at the northern end.
Both smaller, both sheltered, both noticeably quieter than Gylly. Worth knowing when Falmouth is busy.
Small, tucked beside the Island, and sheltered from several directions at once. Genuinely the sun trap of the St Ives beaches, and small enough to feel private early in the day.
Both tucked in behind the headland and considerably more sheltered than Fistral. Central, so easy to reach early without a long drive.
A small sheltered cove on the south coast, with free toilets on site. The south coast in general is calmer than the north, which matters more than people expect.
Enormous, with far more room than St Ives ten minutes away, and the dunes provide shelter. One of the better combinations of space and shelter in Cornwall.
Get the tide wrong and the best beach in Cornwall is useless. On a rising tide you'll be moving your mat every ten minutes; at high water on some beaches there's no sand at all.
Check tide times for the day and aim to start one to three hours after high water. You get firm sand, a falling tide that won't creep up on you, and space that keeps opening rather than closing.
Beach yoga in Cornwall out of season is genuinely better in every way except temperature. The beaches are empty, parking is free or cheap, dog restrictions have lifted, and a still winter morning on an empty Cornish beach is a rare thing. Take more layers than you think and something dry to change into.
