Grassholm (Ynys Gwales) is a small uninhabited island located 13km (8 miles) off the southwestern Pembrokeshire coast in Wales, lying west of Skomer. It is the westernmost point in Wales and is known for its huge colony of gannets. Grassholm has been owned since 1947 by the Royal Society for the Protection of Birds, and is one of its oldest reserves. It serves as a breeding site for 39,000 pairs of the birds. The turbulent sea around Grassholm also provides good feeding grounds for porpoises and bottlenose dolphins.
