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) - NEPTUNE offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Neptune, a steel-hulled trawler, sits upright and largely intact in the eastern reaches of Scapa Flow. It’s a site we consistently recommend, especially for those looking to get a feel for the Flow’s wreck diving without the full commitment of a deeper, darker battleship. Dropping down, you’ll find her at a comfortable 15 metres, making for a long, relaxed bottom time. What we love most about the Neptune is her accessibility and how the marine life has completely reclaimed her. The bow section is particularly good, often draped in dead man's fingers and anemones. You can poke around the wheelhouse, still relatively open, imagining the crew caught in that fateful fog back in 1928. Keep an eye out for inquisitive conger eels peeking from beneath plates and enormous edible crabs scuttling across the deck. It’s a wreck that tells a story, yet feels alive with its new inhabitants. Our pick for a first dive in the Flow, or a satisfying second dive when you’re not quite up for another deep plunge.
