Why dive here
With 140+ marine species recorded in the area - including blue whales, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Wreck of Allan offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Allan, a humble blockship, doesn't get the same fanfare as some of Scapa Flow's behemoths, but we've always had a soft spot for her. Dropping down, you hit the bow first, often enveloped in the perpetual green twilight that makes diving here so atmospheric. You’ll find the wreck relatively intact, sitting upright, with the bow section being our favourite part to explore. Look for the anchor chain disappearing into the gloom. Visibility can be a real character, swinging from 15 metres to a silty five, but even on murkier days, the Allan has a way of revealing herself. Conger eels are nearly guaranteed residents, peeking from nooks and crannies. We’ve also seen nudibranchs, often on the deck plating, so bring your macro lens. It's a great second dive after one of the bigger battleships, offering a calmer pace without sacrificing that distinct Scapa Flow feel. The Allan is a dive for those who appreciate history and don't mind a bit of a treasure hunt in the low light.
