Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - HMS Audacious offers some of West Coast's richest wreck diving. Water ranges 8-17°C, warmest July, August, September.
The HMS Audacious is a proper diver's wreck, plain and simple. We love that it’s a big chunk of history sitting out there in the Atlantic, a King George V-class dreadnought battleship, sunk back in 1914. It’s deep, which means it asks for experienced hands and good planning, but what you get back is pure exploration. Dropping down, the sheer scale of the Audacious becomes apparent through the gloom. You’ll find massive gun turrets, the deck plating peeled back in places, and the superstructure a jumble of twisted metal. Over a century of currents have sculpted the wreck, and marine life has made it home. Conger eels peer from dark corners, their heads surprisingly large, and schools of pollock flit through the skeletal remains of the deck. Visibility can vary wildly here; aim for a calm spell with a northerly breeze if you can. Our favourite moments are finding the smaller details, like portholes still in place, or feeling the cold, silent history of the place around you. It’s a dive that sticks with you, a proper adventure.
