    StandoutExceptional marine biodiversity

    The Marguerita, tucked away in the often-overlooked waters off Cornwall, is one of those wrecks that just makes you smile. It’s barely a dive, really, more a snorkel or a free-dive on a good day. Built in 1919, this old trawler ran aground in 1946 during fierce seas, a tragic loss claiming five lives. What’s left now is a shallow, scattered playground, sitting in maybe two metres of water. We love coming here on a calm day, when the sun can actually pierce the surface and illuminate the broken timbers. You’ll find bits of the hull and superstructure, all well-colonised by local life. Look closely and you’ll spot velvet swimming crabs scuttling amongst the plates and small wrasse darting between the rusty frames. It’s a gentle introduction to wreck diving, perfect for those honing their breath-holding skills or taking underwater photos without the pressure of depth. Our favourite spot is usually around the stern, where the most identifiable wreckage lies. It’s a poignant reminder of a stormy night, now reclaimed by the sea and its creatures.
