Summerleaze Beach, Bude
A wide sandflat at low water with a saltwater sea pool carved into the rocks at its northern end — safer than the open beach on rough days, warmer than you'd expect, and a genuine rite of passage for Cornish children. The walk from the council car park is almost nothing, there are proper loos and a changing block, and the beach has a beach-wheelchair loan scheme. On a clear summer's afternoon with the tide coming in, it's the most civilised stretch of the north coast.
Families with young swimmers. The saltwater pool is the safety net the open Atlantic doesn't give you.
