Southern Mafia boat reef with sandbank stop
Mange Reef is a southern Mafia Island reef best known as a full-day boat trip with a sandbank stop and, in season, whale watching. The site mixes coral reef, sandy patches, and coral bommies, with shallows that work well for accompanying non-divers. It can start as an easy reef look but may turn into a fast drift as conditions build on the outer run.
