Why dive here
HMS Raglan is a wreck dive where divers can encounter dolphins and sea turtles. Water ranges 15-26°C, warmest July, August, September.
The HMS Raglan is a proper historical dive, one of our favourites in Alonissos. This isn't just a pile of metal; she’s a 1915 Abercrombie-class monitor, sunk during World War I, and you really feel that history as you descend. We love picking out the massive gun turrets, still largely intact, and the sheer scale of the ship is impressive as it sprawls across the seabed. Exploring the deck, you'll find clouds of damselfish flitting around the old anti-aircraft guns, and moray eels have made cosy homes in the deeper parts of the hull. The visibility here is usually excellent, giving you clear views of the entire wreck, often with sunbeams piercing through the blue to illuminate the structure. It’s a dive for those who appreciate wrecks with a story, and while it’s not overly challenging, the depth means it’s best suited for experienced divers comfortable with deeper profiles and careful buoyancy control. We always recommend going early in the morning; the light is softer and the currents tend to be calmer.
