Site details

A landlocked, mangrove-fringed marine lake in the centre of Kakaban island, home to millions of stingless jellyfish from several species that have lost their sting in isolation. It is a snorkel-only attraction (scuba is prohibited to protect the fragile jellyfish), reached by a short walk over the island's raised rim. One of only a handful of jellyfish lakes worldwide.
