Diving and snorkelling in Cornwall is a massively popular water activity, so much so that the second largest creature in Cornish waters after the Basking Shark is a PADI trained diver. It is also the only watersport in Cornwall where you can legitimately walk or fall backwards into the sea.

Diving and snorkelling in Cornwall offers you the opportunity to explore ancient shipwrecks littering the Cornish sea bed, or the beautiful labyrynthine Manacles Reef in Falmouth that attracts divers from all over the world. Thousands of divers, often armed with underwater photography equipment descend on the county year after year for a chance to sample the oceanic richness of the Cornish waters.
