    StandoutExceptional marine biodiversity

    The *Hongisto* is a favourite among local divers for good reason. She’s a dangerous wreck, yes, but that just adds to her charm. We love diving her on a calm day, when the visibility opens up to a decent 5-6 metres. You’ll find her broken up, scattered across the seabed in about 9 metres of water, so it’s a perfect site for extended bottom times and really picking through the debris. The stern section is the most intact, with a distinct propeller shaft that stands out. We always spend a good while here, peering into the nooks and crannies. What makes *Hongisto* special is how nature has reclaimed her. She’s absolutely carpeted in plumose anemones, their white tentacles swaying gently in the surge. You’ll spot crab after crab scuttling between plates of rusted metal, and the occasional dogfish tucked away under a larger piece of wreckage. It’s a proper treasure hunt, sifting through the remains, imagining the ship in her prime. This site suits divers who enjoy a relaxed dive, keen on exploring history and observing the smaller, resilient creatures of the Cornish coast.
