    StandoutExceptional marine biodiversity

    The Gallia, a substantial steamship resting at 60 metres, is a serious dive for experienced wreck enthusiasts. This isn't a quick dip; it's a deep, dark exploration that really rewards proper planning. We love how intact she feels despite her age, sunk by a U-boat in 1917. Dropping down, you feel the cold embrace of the Atlantic, and then she emerges, a hulking shadow taking shape. The sheer scale of the Gallia is what really grabs you. Her 91-metre length means there's always more to see, even on multiple dives. We’d suggest focusing on the bow or stern on your first visit, maybe a careful penetration into one of the cargo holds if you’re properly trained and equipped. Look out for the resident conger eels, some of the biggest we’ve ever seen, peering out of every dark recess. Jewel anemones speckle the metalwork with bursts of colour, and we’ve often seen dogfish resting on the deck plates. This is a dive for technical divers who appreciate historical context and the profound silence of the deep. It’s challenging, yes, but immensely satisfying.
