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) - DUNA offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Duna, a steamer lost in 1912, offers a classic Scapa Flow wreck dive. She sits upright at 32 metres, relatively intact for her age, with a real sense of history. We often drop down the shot line onto her stern, where the prop is usually visible, before heading amidships to explore the two large boilers and the triple-expansion engine. It’s a rewarding dive for those comfortable with deeper wrecks and the typical lower visibility of Scapa, revealing a ship now thoroughly colonised by plumose anemones, dead man's fingers, and plenty of fish sheltering in the hold. Just be mindful of the current that can pick up here, especially around slack water changes.
