    StandoutExceptional marine biodiversity

    The Deucalion is a deep, dramatic piece of history sitting upright on the seabed. We love a wartime wreck, and this one, bombed by German aircraft in 1940, tells a story. Dropping down to 58 meters, you find a steamship of impressive scale – 90 meters long, built in the Netherlands. The sheer size of it is what hits you first, a dark mass emerging from the gloom, often cloaked in schooling pollack. Visibility here can be a bit of a lottery, but on a good day, the superstructure is still quite intact, and you can pick out features like the anchor chains or the ghostly remnants of the bridge. It’s a serious dive, definitely for experienced technical divers comfortable with depths and potentially strong currents. Our favourite part? The way the wreck itself has become an artificial reef. You'll often find conger eels tucked into shadowy corners and jewel anemones adding splashes of colour to the corroded steel. It truly feels like stepping back in time, even as modern marine life thrives around it.
