    StandoutExceptional marine biodiversity

    West Bay is one of those sites that just feels like history beneath the waves. You're not looking at a shiny, intact vessel here, but rather a low mound of iron, spread across the seabed at a comfortable 12 metres. We love it because it’s a proper archaeological dive; a protected wreck where the heavily concreted iron bars hint at a cargo lost to a storm, and you can pick out the shape of an old muzzle-loading bronze gun if you know where to look. It’s not about penetration or grand structures, it’s about discovery, about peering into the past. The real beauty here is how the sea has reclaimed it. Every iron bar is a miniature habitat, thick with dead man's fingers and anemones, providing shelter for crabs and blennies. Visibility in Lyme Bay can be variable, but on a good day, with a gentle swell, the ambient light filters down, creating a genuinely atmospheric dive. We'd suggest going on a slack tide to really take your time exploring the details. It's a dive that suits those who appreciate historical context and the quiet observation of marine life making a home on something forgotten.
