    StandoutExceptional marine biodiversity

    The Wreathier is a proper dive, a deep one at 49 metres, so save it for when you’re comfortable with your deco skills. She was a steamship, built in '97, and met her end in 1917, a casualty of the Great War. What we love about her is the way she sits, largely intact, like a ghost ship on the seabed. You can still make out the twin boilers and that huge triple expansion engine, a real marvel of industrial engineering. It's a dark, atmospheric dive, often with a slight chill in the water even in summer, so a drysuit is a must. Visibility can vary, but on a good day, you get a solid 10-15 metres, enough to really appreciate the scale. We’ve seen conger eels the size of your arm snaking through the holds, and the odd inquisitive pollack will often shadow you. Keep an eye out for the vibrant jewel anemones that have colonised the deeper sections, their colours really pop against the muted steel. It's a dive for those who appreciate history and the quiet beauty of a wreck reclaimed by the sea.
