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) - Criccieth Castle offers some of Cornwall & Devon's richest diving. Water ranges 10-18°C, warmest July, August, September.
Criccieth Castle, off the coast of Cornwall, offers a dive focused on exploring the wreck of a small cargo vessel. The structure itself is broken, but we often find spider crabs tucked into the remaining hull sections. It's a decent spot for a shorter dive, generally suited to those looking for a relatively shallow wreck encounter without strong currents.
