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) - GRETA C offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The *Greta C* is a proper deep dive, a carrier vessel that went down in 1974. She sits upright at 53 metres, and while that depth means advanced trimix certifications are a must, the reward is a remarkably intact wreck. We love how her superstructure is still largely in place, offering some fantastic penetration for suitably trained divers. Entering the bridge feels like stepping back in time, the darkness broken only by your torch beam illuminating control panels and the ghostly outlines of equipment. Down on the main deck, the holds are open, revealing the cavernous spaces where cargo once sat. Look closely for conger eels – we’ve seen some absolute monsters lurking in the shadows, their heads poking out from pipes and crevices. The plating is draped in dead man's fingers and colourful jewel anemones, creating a surprisingly vibrant artificial reef. For us, the *Greta C* really shines on those rare days when visibility stretches to 15 metres or more; then you can truly appreciate her scale as you descend through the blue. It’s a serious dive, no doubt, but one that offers a real sense of exploration and a proper challenge.
