    StandoutExceptional marine biodiversity

    The Witte Zee, a tug that sank in 1964, is one of those wrecks that just oozes character. She sits upright at 30 metres, mostly intact, though time and the Atlantic have certainly left their mark. We love descending onto the bridge area; it’s still recognisable, and you can really get a sense of her working life. Inside, the engine room is accessible for those with the right training, a dark, silty delve that feels like stepping back in time. What makes her special? It’s the sheer density of life that has moved in. Pink sea fans sprout from every available surface, their delicate fronds swaying in the gentle surge. Conger eels peer out from behind twisted metal, their eyes following your torch beam. Look closely, and you’ll spot nudibranchs, their vibrant colours a stark contrast to the rust. We’d suggest a slack water dive for the best visibility, which, on a good day, can stretch to 10 metres – enough to appreciate her full 37-metre length. This dive is definitely for experienced wreck enthusiasts who appreciate history and macro life in equal measure. Bring a good torch and take your time.
