Site details

A technical cavern dive on Kakaban island that begins at a crack about 2 m deep and descends through a narrow chimney. Around 21 m the chimney opens into a large cavern extending roughly 120 m, exiting through a long vertical crack in the wall at about 44 m. The name comes from the striking blue glow of the sea seen from within the cavern; it is a deep overhead-environment dive for experienced divers only.
