    StandoutExceptional marine biodiversity

    The Totnes Castle is one of those wrecks we keep coming back to, not for any dramatic story, but for its quiet, dignified resting place. Sunk in '67 on its way to the breaker’s yard, it’s a big steamship, sitting upright in 39 metres of water, offering plenty to explore. We love finning over the deck, imagining its last journey, before dropping into the holds. Inside, light filters through gaps, illuminating the skeletal remains of its machinery. The wreck’s structure is home to a good number of bib and pollack, constantly darting in and out, and you’ll often spot a conger eel peeking from a dark corner. The stern, in particular, has some lovely soft corals draped over it, a real burst of colour in the ambient light. It’s a good dive for those comfortable with deeper wrecks and who appreciate the slow, methodical exploration of a vessel that’s become an artificial reef. Visibility here can be tricky, so pick a day with minimal swell for the best experience.
