Skomer, Skokholm & Grassholm Islands

Just off the southern headland of St Bride's Bay lie the three islands of Skomer, Skokholm and Grassholm, all part of a marine reserve. Best known for their vast colonies of sea birds and seals they are busiest at the height of summer, but in autumn the seals have pupped and you can also sport dolphins and poroises in the waters.

Skomer is the biggest of the islands, covering 722 acres, and the most accessible. There are actively breeding colonies of puffins, cormorants, razorbills as well as plenty of other seabirds. Skomer and Skokholm between them represent the world's biggest colony of Manx sheartwater and there is accommodation available on Skokholm.

Grassholm is the smallest of the three islands and best known for its colony of (very noisy) breeding gannets. It is not possible to disembark, but you can do round trips of the island by boat.
