The SWT – which receives funding from the Esmée Fairbairn Foundation – has also confirmed that Scotland's first snorkel trail has been created in the north west Highlands. The idea is that the snorkel trail is self-led.

Tourism Secretary Fiona Hyslop stated “The snorkel trail is an innovative approach to marine and coastal planning that encourages use of existing infrastructure to help tourism diversification like this."

The 10,850-ton armoured cruiser HMS Hampshire departed Scapa Flow in Orkney on 5 June 1916 on a voyage around the north cape of Norway to the port of Archangel in northern Russia. She was carrying Lord Kitchener, the Secretary of State for War, and his staff to Russia to discuss mutual war aims and strategy.

From Churchill's blockships dotted along the rugged coastline, to dramatic battleships, the wrecks of Scapa Flow continue to fascinate and enthrall divers.
