    StandoutExceptional marine biodiversity

    The Merkur sits in a shallow churn of water, making it one of our favourite wreck dives when the weather isn’t playing ball for the deeper stuff. We're talking 10 metres, maximum, so it’s an ideal second dive or a relaxed day out for newer wreck enthusiasts. She went down in 1920 after a collision, and what’s left of her now forms a series of scattered plates and ribs, softened by time and the sea. This isn’t a wreck where you're finning through intact corridors. Instead, we love picking through the smaller, more broken pieces, uncovering engine parts and twisted metal. It’s less about penetration, more about the archaeology of the site, seeing how the structure has completely given over to the ocean. Look closely and you’ll find plenty of crabs tucked into crevices, their antennae twitching, and often a few inquisitive dogfish slinking around the edges of the debris. Visibility can be a bit variable here, especially after a good blow, but on a calm day, with a bit of sun filtering through, the metal gleams, and the gentle current makes the kelp sway around the wreckage. We’d suggest going at slack water, if you can time it right, to really take your time exploring the nooks and crannies.
