dive site map
Dive sites in Indonesia.
An Indonesia dive site map, with diving spots in Raja Ampat, Komodo, Tulamben, and Bali.
Search for a place. A point on the map opens the depth, the way in, and a button to start the trip in Google Maps.
These points use published coordinates. The mooring on the day can sit a little off the pin, so confirm it with your dive guide before you splash.
