HMS Fiona - Scapa Flow, Orkney

Diving the HMS Juno in the Dodecanese is like stepping onto a forgotten stage. This K-class destroyer, sunk in 1941, doesn't just sit on the seabed; it commands it. We’ve finned over plenty of wrecks, but the Juno has a powerful, almost mournful presence, broken up enough to be interesting but coherent enough to recognise its original form. The bow section is a particular highlight, often swarming with schools of fusiliers that stream past like liquid silver, occasionally parting to reveal a curious loggerhead turtle cruising the deck. Inside, the light often plays through the crumpled metal, illuminating boa dragonfish that hug the shadows. Exploring the engine room area, where the metalwork is more abstract, feels like navigating an alien landscape. Visibility here can vary, but on a good day, when the sun penetrates the depths, the Juno offers an atmospheric dive that stays with you long after you’ve surfaced. Our pick for best conditions is late morning, before any stronger afternoon breezes stir the surface.
