Trefor Pier - Cornwall & Devon
Trefor Pier, on the Cornwall coast, offers a straightforward pier dive for those seeking macro life. We’ve found nudibranchs and small crabs tucked into the pier legs, with occasional sightings of dogfish on the sandy bottom. Visibility can be hit or miss, but on a good day, it’s a calm entry, making it decent for newer divers or those looking for an easy shore dive. It’s not a showstopper, but it has its quiet charm for a local dip.
