Porthoustock - Cornwall & Devon

Porthoustock is a decent pick for a relaxed shore dive, especially if you’re new to the Cornish scene or just fancy a gentle potter. It’s a shallow affair, topping out around 9 metres, which makes it perfect for longer bottom times and really getting comfortable with your buoyancy. You’ll generally find decent visibility here, letting you spot the usual UK suspects – plenty of wrasse darting through the kelp, crabs scuttling over the rocks, and the occasional dogfish tucked away. It's an easy entry from the beach too, so a good spot for dive groups with varying experience levels or for knocking out some practice drills.
