    StandoutExceptional marine biodiversity

    Plaston is a standout site for a very specific kind of diver, and we love it for its moody, evocative feel. This isn't a deep dive, sitting at a maximum of 11 metres, but what it lacks in depth it more than makes up for in atmosphere. We're talking about a genuine historical wreck here, and the age shows in the way the ship’s structure has softened, becoming part of the seabed. What you'll experience is a relatively intact, though flattened, steam trawler, Plaston. Her engine room is still identifiable, and you can swim through areas where the hull has peeled back, creating swim-throughs that feel like exploring a forgotten attic. Light filters down in muted greens and blues, making the metal glow. Conger eels are a common sight, tucked into the dark recesses, and the wreck itself is absolutely smothered in jewel anemones, hydroids, and dead man’s fingers, making it a vibrant, living sculpture. It's a fantastic spot for photographers who appreciate the interplay of history and marine growth. We’d suggest diving it on a slack tide for the best visibility and to really take your time exploring the nooks and crannies. If you enjoy a wreck with a story, one that feels truly ancient and reclaimed by the ocean, Plaston is our pick.
