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) - MALLENY (OR MALLENEY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
Malleny, or Malleney, sits low on Tusker Rock, a sombre reminder of that October night in 1886. At just two metres deep, it's less a deep exploration and more a shallow archaeological stroll, perfect for a long snorkel or a gentle dive when the tide is high and calm. We find its accessibility incredibly charming; you can spend ages poring over the scattered timbers without worrying about narcosis or deco limits. What remains of the 62-metre sailing vessel is strewn across the seabed, a jumble of ribs and hull plates colonised by the resilient life of the Cornish coast. Look for the glint of wrasse darting between the rusted ironwork, and the patient sway of kelp fronds, providing cover for velvet swimming crabs. It’s not about grand swim-throughs here; it’s about the quiet contemplation of history, feeling the gentle surge over the wreck, and appreciating the surprising density of small creatures clinging to every surface. This site is our pick for anyone who loves history and the simple joy of an unhurried shallow dive, particularly good on a sunny, slack tide day.
