Rainbow Reef - Grand Cayman
We love a shallow wreck, especially one so close to shore. The Clan Stuart, a coal steamer grounded in 1914, sits in just 8 metres of water, meaning serious bottom time. You’ll find her off Simon’s Town, a quick swim out from the beach, and what a swim it is. We’ve spent hours poking around the engine block, still largely intact, and the propeller shaft. Inside the collapsed holds, it’s a mosaic of colourful tube corals and bryozoans. Outside, the exposed metalwork is coated in vibrant red bait and coralline algae, drawing in schools of juvenile silver moony and shy sand steenbras. Keep an eye out for mimic blennies peeking from crevices – they’re a favourite. Visibility averages about six metres, which is decent for a shallow coastal site, giving the wreck a wonderfully atmospheric, slightly spooky feel. It's a fantastic site for newer divers or those who prefer a relaxed, long dive without the pressure of depth.
