IONION (PROBABLY) - Crete
The Ionion (Probably) is one of our favourite easy wreck dives in Crete, and a site that makes for a surprisingly good second dive. Lying in just 5m of water, this Roll-on/Roll-off ferry sank back in '92, and the decades have been kind to it. We love the way the shallow depth lets sunlight flood the wreck, illuminating the big cargo holds and open vehicle decks. You can spend a whole bottom time just gliding over the skeletal superstructure, watching schools of damselfish flit through the old passenger areas. It’s a great spot for newer divers to experience a proper wreck without any depth anxieties, and for photographers, the ambient light is fantastic, especially mid-morning. Look closely at the hull plates for nudibranchs, and keep an eye out for octopus tucked into crevices. The wreck is pretty broken up in places, but the sheer scale of it still impresses. We'd suggest going on a day with minimal surface chop to really appreciate the visibility.
