    The U 122 is a proper deep dive, a real journey into history off the Cornish coast. At 53 metres, you’re looking at serious decompression time, so this one's for the experienced technical diver, no question. We love the eerie stillness down there, the way the light struggles to penetrate, making the wreck feel even more isolated. This isn’t some broken-up debris field; it's a remarkably intact U-boat, scuttled nearly a century ago. Gliding along her 82-metre length, you can still make out the conning tower, the torpedo tubes, even some of the deck guns. It’s heavy metal, a stark contrast to the colourful reefs we often chase. Instead of tropical fish, expect to see the wreck encrusted with plumose anemones, their white tentacles swaying gently in the subtle current, like a ghostly choir. Big conger eels have made homes in the superstructure, their heads poking out from dark openings, watching you drift past. We always find ourselves pausing at the bow, trying to imagine the ship's final moments. Visibility can be hit or miss, but on a good day, when the water is green-blue and clear, the scale of the U-boat is genuinely impressive. Our favourite time to dive it is late summer or early autumn when the plankton blooms have cleared a bit. Bring good lights; you’ll want them to peer into the shadowed sections.
