StandoutExceptional marine biodiversity

Millisle is a proper Cornish wreck, lying deep but beautifully intact for its age. We’ve spent some fantastic deco time on the stern, just watching the conger eels slip in and out of the plating. She went down in 1941 carrying coal, and that cargo is still visible in the holds, adding a strange texture to the darkness. The boiler is a standout, a huge, looming presence where shoals of pollock often gather, creating a shimmering curtain when your torch beam hits them. Visibility here can be a lottery, typical for the Channel, but on a good day, the sight of her masts stretching upwards from the seabed is genuinely moving. It’s a site for experienced divers, comfortable with depths down to 40 meters and a bit of current, but the rewards are there. We love the way she’s settled, offering plenty of swim-throughs and sheltered nooks for crabs and lobsters. Our advice? Go at slack water, bring a good reel, and take your time exploring the bridge area. That’s where we’ve had some cracking encounters with curious ballan wrasse.
