la caverne d'Albi baba is a deep Poindimié trench dive where a blue-water drop-off leads into a chimney and cavern above the trench ridge. The site is built for experienced scuba, with big pelagic energy around the exit and a profile that rewards calm conditions, solid buoyancy, and close guide control. Boat timing and steady buoyancy matter because the trench approach and cavern section leave little margin for sloppy movement.
