MORE Top UK Snorkelling and Freediving Experiences

Many organised group activities got cancelled from our calendars during recent lockdowns and restrictions. If you’d had some experience with snorkelling and freediving, you could have done these activities with your family, not too far from home and with minimal equipment. If you weren’t lucky enough to live by the coast or be a seasoned water baby, perhaps now if the time to explore the coastline on this year’s staycation and learn a new skill.

Our list below includes some more of the UK’s best snorkelling and freediving destinations. Please see our earlier blog Top 5 Snorkelling Experiences for further suggestions. 


Porthkerris, Cornwall

Located in a secluded cove along the Lizard peninsula, Porthkerris is in a Marine Conservation Zone. It has some spectacular snorkelling from the shore, while The Manacles can be reached by boat. Below its vertical cliff faces are rocky reefs with large boulders embedded in a sandy bottom. There is plenty of marine life to see in this area from cuttlefish to John Dory and snakelocks anemones. From June onwards, blue sharks appear offshore to enjoy a diet of squid. They are easily identified by their blue/silver back, slender body, long pectoral fins and big eyes.

St Abbs, Scotland

Established as a marine reserve in 1984, the coastal waters of Berwickshire stretch from Eyemouth to St Abbs Head. Healthy kelp beds, rocky shores and deep gullies make for some spectacular snorkelling where you are likely to find sea hares, crabs and wolffish. Cliff faces covered in soft corals, hydroids and anemones will demand your attention, but keep one eye behind you as bigger mammals like grey seals, minke whales and harbour porpoises might pass by in the blue!
