Possibly the most western beach in the guide, Periglis sits on the far side of St Agnes with just Annet and the Western Rocks between it and the coast of America.
The beach here is a crescent of coarse, white sand which curves around a small natural harbour with Burnt Island to the north offering the bulk of the shelter. There are twin slipways here, one of which used to form part of the St Agnes lifeboat slip. Between 1890 and 1920 the island had its own lifeboat station owing to the frequency of shipwrecks on this most western of the inhabited islands.
Now-a-days Periglis is yet another quiet Scillonian beach with safe swimming, plenty of rock pools and stunning views to Bishop's Rock lighthouse and beyond.
