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) - LLANISHEN offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Llanishen isn't one of Scapa's usual German fleet wrecks, and that's precisely why we love her. This British steamship met her end in 1940, bombed by German aircraft, and now lies split in two at 50 metres. Descending, you’ll first hit the stern section, a chaotic jumble of plates and machinery, home to nudibranchs and squat lobsters tucked into every crevice. Our favourite part is navigating the debris field between the stern and bow, where the light fades and the sheer scale of the sinking becomes apparent. The bow section is the more intact of the two. We always head for the anchor chains, draped like thick necklaces, before peering into the open holds. The water here feels heavy, green, and cold, typical of Scapa, but the visibility often pushes 15 metres, giving you time to appreciate the immense structure. This is a dive for experienced deep wreck enthusiasts, comfortable with deco and a bit of overhead penetration if you’re keen to explore the deeper holds. It’s a proper Scapa dive, raw and historical, without the crowds of some of the more famous sites.
