River of Sands - Grand Cayman
Sunset Rocks, just a quick hop from Beau Vallon, always feels like a bit of a secret. We anchor up on the sand and drop onto a low-slung world of granite boulders, a truly unique change from typical coral reefs. It’s shallow, topping out at maybe 12 meters, making it perfect for a leisurely meander. The currents here can be a bit of a mixed bag; sometimes it’s a gentle drift, other times you’re really flying, which just adds to the adventure. We love watching for the smaller stuff that takes refuge amongst the rocks – those pipefish are masters of disguise, and we’ve spotted stonefish here more than once, so keep those eyes peeled. Schools of fusiliers often swirl in the blue, and on a good day, the light plays through the water, making the granite glow. While the corals aren't the main event, the formations themselves are spectacular. This site is our pick for divers who appreciate the subtle beauty of a rocky reef and don't mind a bit of current to keep things interesting.
