    StandoutExceptional marine biodiversity

    The *Glenlee* is a proper wreck dive, a big steamship sitting upright and broken across the seabed. She went down fast after hitting a mine in 1918, and that history really comes through when you’re down there. We love poking around the bow, which is separated but still impressive, or heading aft to where the engine room should be. The visibility can be a bit hit or miss in Lyme Bay, but when it’s good, you can appreciate the sheer scale of her: 121 metres of history colonised by the sea. Expect to see plumose anemones carpeting the metalwork and big shoals of bib darting through the holds. Conger eels are often lurking in the darker recesses, and if you bring a torch, you’ll spot crabs tucked into every crevice. We’d suggest diving this one on a slack tide for the best exploration, especially if you want to get a good look at the triple-expansion engine. It’s a site for experienced wreck divers who appreciate the story behind the metal and the hardy marine life that thrives in temperate waters.
