Cobalt Ridge - Grand Cayman

The Southwest Coast of Grenada is a wreck diver’s playground, and while there are plenty of options, we think the *Bianca C* tends to steal the limelight from some real crackers. For a different vibe, dive into a few of the lesser-known sites, especially the one simply known as "Grenada". It’s a shipwreck, maxing out at 19 metres, making it super accessible for most divers. We love this spot for its quiet charm. You can easily spend an hour exploring the broken superstructure, which has been beautifully colonised by sponges and soft corals. Keep an eye out for the resident barracuda patrolling the mast, and those Sharpnose Pufferfish peeking from every nook. On our last trip, we spotted several Spotted Trunkfish, just hovering in the gentle current, and the Blue Parrotfish were everywhere. Visibility averages around 16 metres, which is decent enough for some great photo opportunities. It's a relaxed dive, perfect for photographers or anyone who enjoys a leisurely poke around a historical wreck without strong currents.
