The easiest adventure from Kirkwall is south to the two rocky isles, once only accessible by boat, now linked by causeway but still retaining a special island-like character, and lined with sandy coastal hikes. The causeways that link these isles, the Churchill Barriers, protect Scapa Flow, one of the world’s largest natural harbours and a fantastic spot for snorkelling or wreck diving. South Ronaldsay has a couple of small campsites, with glamping pods and pre-erected bell tents also available. You can also explore different options for camping near Kirkwall on Hipcamp.
