    StandoutExceptional marine biodiversity

    The Pentyrch is a proper dive, a deep cut into history sitting at 17 metres. We’re talking about a WWI steamship, torpedoed and sunk by a German U-boat in 1918. It’s definitely a melancholic place, knowing its story, but that history is what gives it so much character. What you find now is a wreck largely collapsed but still very much a wreck, spread across the seabed. The bow and stern sections are the most coherent, giving you a real sense of its former scale. The midships are more of a debris field, but don’t dismiss it – that’s often where we find the most interesting stuff. Conger eels love these scattered plates, and we’ve seen some huge ones tucked away. We’ve also had fantastic drifts over the whole site on a good tide, watching dogfish scout the edges and enormous ballan wrasse pick their way through the plating. Visibility can be a typical Cornish mixed bag, but when it’s good, the light penetrating to the seabed here is just beautiful, silhouetting the remaining ribs. This is one for wreck enthusiasts who appreciate the story as much as the structure, and for those who enjoy hunting for the resident marine life in a more somber setting.
