DEN OF SEATON - Cornwall & Devon

The Den of Seaton is proper wreck diving, pure and simple. We love that it’s still very much a ship, not just a pile of plates, especially with those huge boilers standing proud at 27 metres. Dropping down, you’ll often hit a bit of murk at the surface but punch through to surprisingly good visibility on the deck. Look for the bow section, it’s often buzzing with pollock and wrasse darting in and out of the twisted metal. We always suggest taking a good torch, not just for peering into the gloom, but to pick out the jewel anemones and dead man’s fingers that cling to every surface. Our favourite part is exploring the cargo holds, if you’re comfortable with overhead environments. The sheer scale of the Den of Seaton, at over 100 metres long, means you’ll need multiple dives to even begin to get a feel for it. It’s a site that rewards patience and good buoyancy control. If you’re into proper historical wrecks that still hold their shape, this one’s a standout. Be mindful of currents, they can pick up quickly, so always check the tides before you head out.
