Ramsey Island lies about 1 km off the coast of the St David's peninsula in Pembrokeshire, southwestern Wales, UK.
Owned by the RSPB, the island has spectacular sea bird cliffs, coastal scenery and heathland. Ramsey has the most important grey seal breeding colony in southern Britain, and is one of the best sites in Wales to see choughs. Other breeding species include ravens, buzzards, peregrines, wheatears, gulls and auks.
With a permanent population of just 2 residents, (the warden and his wife), the island is otherwise uninhabited. Tourist boats sail to the island (7 days a week, Easter-31 October) from St Justinian's on the mainland.
