Sheltered Chole Bay seagrass and coral tongues
Corinne’s Reef is a sheltered Mafia Island boat dive in Chole Bay, built around shallow seagrass beds, sandy lanes and three coral tongues that keep the site interesting without making it complicated. It is a relaxed, beginner-friendly profile with easy-reading terrain rather than deep walls or heavy flow. Plan it for calm water and good tide timing, then look for snake eels, nudibranchs, resting rays, green turtles and big schools of fish along the sand and weed.
