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) - ST KILDA offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The St Kilda wreck, a former motor vessel that went down in 1961, rests at 36 metres. She’s a decent size at 37 metres long, and while the structure is well broken up now, the sheer scale of the debris field is impressive. We usually find conger eels tucked into the larger sections, and the metalwork attracts plenty of bib and pollack. It’s a site for divers comfortable with depth and navigating a scatter, offering a good glimpse into the working history of these waters.
