    StandoutExceptional marine biodiversity

    The HERLILLE, a fishing trawler that went down off Slangkop in '78, is a deep dive, sitting around 50 metres. That depth alone means it’s not for everyone – you need the right training and comfort level. But if you’ve got that, what awaits is a seriously atmospheric wreck. We love how the hull is pretty much intact, resting upright on the seabed. You can see the superstructure, even some of the fishing gear, all slowly being reclaimed by the ocean. Swimming along the deck, you’ll spot a surprising amount of soft coral growing on the metal, little bursts of colour in the deep blue. Our favourite part is peeking into the wheelhouse, imagining the last moments before she went down in those heavy seas. Look for the schools of hottentot darting in and out of the darker corners, and the occasional shy octopus tucked away in a crevice. It’s a dive that really makes you feel the history, a quiet, respectful experience with a genuine sense of solitude. Go on a calm day, it makes the descent and ascent a lot more comfortable.
