About Porthoustock
Porthoustock is a sheltered shore dive on Cornwall's Lizard Peninsula, with a shingle beach, a harbour wall, and a shallow kelp forest that gives the site a lot of structure for a short swim. It is a classic training-friendly dive with easy entry, simple logistics, and a mix of sand, rock, and kelp habitat. The site rewards relaxed buoyancy and a careful eye on the surface, since the shallow profile makes it approachable but the surrounding working-water context still asks for good awareness.
