Brings you the best marine ecotourism experiences in Europe

Hatt Rock lies about 10 miles south of Looe. It is only suitable for advanced divers and is a flat-topped pinnacle that starts about 25 meters down and then falls steeply to around 70 meters with ledges full of life.  With nothing else around the top of the rock, it’s like being on a mountain top in a wilderness.

Considered by many the finest scenic dive in Cornwall, the marine life that can be seen here includes branching sponges, pink sea fans, plumrose anemones, soft corals, sea urchins and large shoals of mackerel and pollack.
