Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Trefor Pier offers some of Cornwall & Devon's richest reef diving. Water ranges 10-18°C, warmest July, August, September.
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.
