Brings you the best marine ecotourism experiences in Europe

Just off Trevelgue Head at the eastern end of Newquay Bay lies a hidden rock that is ideal for shallow dives and photography. At 15m at the deepest point this is suitable even for novice divers who have some experience of open water. Gullies and tunnels radiating out from the rock contain a huge variety of marine life including corals and crustaceans. In the summer, spider crabs in their hundreds have been known to congregate here to breed.

Nearby the Milky Rough Reef is a shallow sheltered reef full of exceptionally large star fish up to 2ft across. It is a circular reef surrounded by sand and is another ideal novice dive. There are also several gullies to swim through.
