Grassholm Island is a tiny white speck of land, 11 miles from the coast. As you approach the island, you begin to understand why it's white. It's home to the only gannet colony in Wales and second largest in the UK. Not only are the rocks stained white with droppings but the air is white too, with thousands of gannets on the wing. The island is a RSPB bird sanctuary.
Catch a boat from Martins Haven on Mondays at 2pm or from St Justinians. No landing is permitted.
