Site details

Wailea's go-to training and refresher shore dive: a calm sandy entry between two rocky points, with reef beginning in a few feet of water and extending along a lava point to 20-45 ft on the outer reaches. A turtle cleaning station makes honu sightings likely. The easiest entry/exit in South Maui, heavily used by instructors for first ocean dives.
