The U-722, a German Type VIIC U-boat, lies in the chilly embrace of the Scottish West Coast, a ghost from the Battle of the Atlantic. We love this wreck for its sheer presence, the way it just *sits* there, mostly intact, an echo of wartime history. Dropping down, you’re met with a surprisingly good silhouette, even in the sometimes murky green; the conning tower still stands proud, and the deck gun is often visible. It’s a proper expedition dive, no two ways about it, suited for experienced cold-water wreck enthusiasts who appreciate the atmosphere more than tropical colours. Inside, where accessible, you can glimpse the machinery that once powered this predator. It’s dark, naturally, and the silt demands good finning technique, but the satisfaction of finning through a piece of history is immense. Look for the resident conger eels, they’ve made the U-boat their own, and often poke their heads out from unexpected crevices. Our advice: pick a calm day with minimal swell, and factor in the strong tidal currents – slack water is your friend here. It’s a dive that stays with you, a poignant reminder of a conflict long past, now a vibrant artificial reef.
