    StandoutExceptional marine biodiversity

    We love a good mystery, and the Lass O'Doune (probably) delivers. Dropping onto her at 16m, you’re immediately struck by the sheer presence of this old trawler. Built in 1910, she’s been down since 1946, and the years have draped her in a thick, green-brown coat of life. We often find conger eels peering from dark recesses, their thick bodies camouflaged against the rust. The wreck itself, while small at 26.2m, is surprisingly intact and offers some fantastic swim-throughs if you're comfortable with overhead environments and have good buoyancy. Her single boiler is still prominent, a massive cylinder encrusted with jewel anemones, shimmering orange and pink in your torch beam. This isn't a site for spotting megafauna, but if you enjoy history, close-up invertebrate life, and the quiet satisfaction of exploring a well-aged wreck, it’s a cracker. Visibility can vary wildly here, so pick a calm day with a neap tide for the best experience. The atmosphere is undeniably moody, a real sense of history under the waves.
