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 Cornelia offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
Diving the Cornelia in Scapa Flow, you’re not just exploring a wreck, you’re touching a piece of history. This Blockship, deliberately scuttled in 1915 to protect the naval base, lies upright and relatively intact, making it a fantastic dive for those who appreciate the story behind the metal. We love the way the light filters through the structure, illuminating vast schools of saithe that swirl around the bow, a shimmering curtain of silver against the dark steel. Our favourite part has to be finning through the open holds, feeling the chill embrace of the Orkney water, and seeing how the marine life has utterly transformed the vessel. Ling cod lurk in shadowed corners, their mottled skin blending perfectly with the encrusted metal. Look closely and you’ll spot plumose anemones blooming like alien flowers, their white tentacles swaying with the gentle surge. It’s a dive that rewards slow exploration, peering into every nook and cranny. We’d suggest a good torch, not just for the darker sections, but to really pick out the details – the rivets, the rusticles, and the vibrant colours of the invertebrate life clinging to every surface. This is a dive for the curious, for those who want to feel the weight of history and witness nature's relentless reclamation.
