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) - SAINT LOUIS offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Saint Louis sits deep, a proper technical dive at 47 metres, so come prepared for the chill and the planning involved. Sunk back in 1884, this old sailing vessel is now a classified dangerous wreck, meaning it's well broken up, but that just adds to its character. You’ll find ribs and plating scattered across the seabed, creating hidey-holes for conger eels and squat lobsters. It's a site for those who appreciate the history beneath the waves and the quiet solitude of a deep exploration, rather than a swim-through.
