Ramsey Island

St Davids (Tyddewi)

Ramsey Island (Ynys Dewi) lies off the headland to the west of St Davids, ringed by dramatic sea cliffs and an offshore armada of rocky islets and reefs. The island is a Royal Society for the Protection of Birds (RSPB) reserve famous for its large breeding population of choughs – members of the crow family with glossy black feathers and distinctive red bills and legs – and for its grey seals.

You can reach the island by boat from the tiny harbour at St Justinian, 2 miles west of St Davids. Longer boat trips run up to 20 miles offshore, to the edge of the Celtic Deep, to spot whales, porpoises and dolphins. What you'll see depends on the weather and the time of year; July to September are the best months. Porpoises are seen on most trips, dolphins on four out of five, and there's a 40% chance of seeing whales. The most common species is the minke, but pilot whales, fin whales and orcas have also been spotted.

Thousand Islands Expeditions is the only operator permitted to land day trippers on the island, where they can explore some of its 3½-mile walking circuit. Voyages of Discovery, Aquaphobia and Venture Jet head out to the island but don't land there.
