Wreck of Arcturus - Scapa Flow, Orkney

Diving the Arcturus in Scapa Flow is less about grand, intact structures and more about an intimate exploration of a ship coming apart. We love that it’s scattered, almost like a puzzle waiting to be pieced together in your mind. You’ll descend into a world of twisted metal, with plates peeling back like pages, creating fantastic nooks for the local critters. Look closely for the wolfish lurking in the gloom, their eyes glinting, and we've spotted some impressive ling slinking through the larger gaps. It's a proper rummage, best suited for divers who enjoy poking around and appreciating the smaller details rather than swimming along a full deck. The visibility here can be… moody, so bring a good torch and keep your buoyancy dialled in. We'd suggest going at slack tide; it makes navigating the debris field much more pleasant.
