Diving Indonesia

The world's richest reefs, one practical guide.

Indonesia sits at the heart of the Coral Triangle, home to more marine species than anywhere else on Earth. Manta cleaning stations in Komodo, the impossibly rich reefs of Raja Ampat, mola mola off Nusa Penida, the bizarre critters of Lembeh, Bunaken's sheer walls and the untouched coral of Wakatobi. But with 17,000 islands, seasonal currents and liveaboards that book out months ahead, planning the right dive trip is hard.
