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) - NAJA (PART OF) offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Naja isn't a deep dive, that's for sure. At two metres, it’s practically snorkelling, but it’s still one of our favourite surface interval explorations in Scapa Flow. This concrete barge, deliberately sunk in 1939 as a blockship, offers a surprisingly intricate delve for how shallow it sits. We love poking around the broken hull sections; you can really get a sense of its robust construction. The concrete provides a fantastic substrate for anemones, and we often spot butterfish darting through the cracks. It’s a great little drift if there's a bit of current, and it’s perfect for those calm, sunny Orkney days when the light penetrates right to the seabed, illuminating the sponges and kelp. Honestly, it’s a site that proves you don’t need depth for character.
