Wreck of Hylas (Possibly) - Scapa Flow, Orkney
The HMT Royal Edward offers a profound dive, a proper piece of history right here in the Mediterranean. We love a wreck with a story, and this former troopship, sunk in 1915, tells a grim one. You descend onto what feels like a ghost, an enormous, broken hull resting on the seabed, typically in pretty good visibility that lets the full scale sink in. Expect to see vast sections of the ship’s structure – ribs, decks, and bulkheads – now heavily encrusted and serving as artificial reefs. Schools of white seabream drift through the shadows, while wrasse pick at the growth. Look closely, and you'll spot red lionfish tucked into crevices and the occasional marbled spinefoot grazing on algae. The Royal Edward isn't about intact cabins or machinery; it's about the sheer size and the feeling of diving through a moment frozen in time. This dive suits experienced wreck divers who appreciate historical context over colourful corals. The depth and potential currents mean it’s not for beginners, but for those with the skills, it’s a truly humbling experience.
