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 Unnamed Shipwreck - Canmore 101746 offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The St. Nicholas is one of those wrecks that really tells a story, even if you’re not a history buff. We’ve always been drawn to how she rests, keeled over on her port side, almost like she’s taking a final, weary bow. Dropping down, you’ll find yourself navigating through a skeleton of steel, with huge boilers and machinery creating dramatic swim-throughs. The light filters in so eerily here, especially on an overcast day, turning the interior into a muted, silver-grey world. It’s the sheer scale of the cargo holds, now open to the sea, that we love most. They’re like vast empty chambers, but not truly empty. Beadlet anemones cling to every surface, and we’ve seen dogfish tucked into crevices, quite unbothered by divers passing by. Watch for common whelks slowly traversing the plating. This is a dive for those who appreciate the quiet grandeur of a historical wreck, where the marine life adds texture rather than stealing the show. Best to visit on a calm day; Scapa Flow can get choppy, making the descent less comfortable.
