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) - NEPTUNIA offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
For us, the Neptunia is a proper dive, a deep plunge into Scapa Flow's history that demands respect. This German merchant ship, sunk in 1919, rests upright at 60 metres, and the sheer scale of it hits you the moment you descend. We love seeing the bow loom out of the gloom, usually a muted green light filtering down, and the stern rises impressively towards shallower depths. The hold is our favourite part, though. Dropping inside, it’s a vast cavern. You’ll find light shafts piercing the darkness from the deck openings above, illuminating the occasional squat lobster or a schooling pollack that has made it home. We’d suggest focusing on the aft section and the superstructure; the bridge area is especially photogenic with its encrusting anemones and sponges. Visibility can vary wildly here, but on a good day, the sense of immersion in maritime history is total. This isn't a dive for the faint of heart or the inexperienced; the depth and potential for current mean you need to be on your game, but the reward is a genuinely captivating wreck experience.
