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) - GEFION offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The *Gefion* is one of our favourite wreck dives in Cornwall, a genuine standout. This steamship met its end in 1917, now resting upright at 33 metres, her stern nicely intact. You’ll fin down, feeling the colder thermocline, then suddenly the dark shape emerges, huge and imposing. The bow section is a bit more broken up, but the midships, with its two big boilers and the triple-expansion engine, offers some fantastic penetration for suitably trained divers. We’ve seen some hefty conger eels here, tucked deep inside the machinery, their heads peering out. The structure itself is just covered in anemones and dead man's fingers, a riot of colour against the dim light, especially when a torch beam hits it just right. It’s a dive that rewards careful exploration, not just a quick swim-over. We’d suggest a slack water dive for the best experience, as the currents can pick up and make finning around the deeper sections quite challenging.
