CROMA - Scapa Flow, Orkney

We’ve always had a soft spot for Scapa Flow’s smaller wrecks, and the Croma is a solid example of why. This steamship, sunk back in 1890, sits upright at around 15 metres. You’ll find two large boilers quite prominent amidships, and the compound expansion engine is also visible, a nice glimpse into Victorian engineering. The wreck itself has become a home for lobsters and crabs, tucked into crevices, with shoals of wrasse often darting between the plates. It’s a gentle dive, perfect for those looking to explore a piece of history without deep-diving technical demands.
