    StandoutExceptional marine biodiversity

    Le Poilu isn't your average pile of twisted metal. This ketch, sunk off Sark in 1921, sits upright and surprisingly intact, and that's why we love it. Dropping onto her deck at 20m, you immediately get a sense of her shape, the bow pointing into the current, the stern slightly deeper. It’s not a huge wreck, but she’s beautifully colonised. You’ll find walls of plumose anemones swaying in the gentle surge, especially around the mast step and the intact bow section. Look for lobsters tucked into any crevice, and big conger eels often peek out from under the collapsed deck plating midships. The hold is still accessible, offering a dark swim-through that always gives us a shiver, but keep an eye out for dogfish resting on the silty bottom. This is a brilliant dive for those who appreciate history and macro life, without battling strong currents. Go on a slack tide for the best visibility; it just opens the wreck up.
