    StandoutExceptional marine biodiversity

    The Haytain, sitting at a shallow 8 metres, is one of our top picks for a wreck dive that feels genuinely accessible, even if you’re newer to wreck exploration. She went down in ’41, and while time has stripped away a lot of her superstructure, what’s left is a really engaging set of ribs and plates scattered across the seabed. We love poking around the deeper sections of debris, where lobsters and edible crabs often peek out from under the metal. You’ll find squat lobsters clinging to the exposed steel girders, their tiny claws waving in the gentle surge. For us, the Haytain is less about a grand ship and more about the intricate ecosystems that have colonised the remains. Look for conger eels tucked into the larger sections, and if you go on a calmer day, the ambient light filtering down makes the bronze-hued algae covering the wreck glow. It’s a site that rewards slow, careful exploration rather than just a quick swim-through.
