Blue Bay sits on the southeast coast of Mauritius and is a designated Marine Park in the Indian Ocean. Conditions here are mild with good visibility and an absence of strong currents, making it one of the most accessible diving areas on the island. The site mix spans shallow shore-entry reef at a few metres through to wrecks, walls, caves, and canyons reaching around thirty metres, so beginners and intermediate divers both find suitable dives. Reef life includes green sea turtles, emperor angelfish, blacktip and whitetip reef sharks, and a variety of wrasses and parrotfish.
