Diving Indonesia

Indonesia is the heart of the Coral Triangle—the most biodiverse marine region on Earth. With over 17,000 islands spanning 5,000 kilometers, this archipelago offers diving experiences found nowhere else.

I’ve been diving Indonesia since 2005, working on manta ray and whale shark research across the country. These are my top recommendations.

Top Destinations

Raja Ampat

The world’s most biodiverse coral reefs. Over 1,500 fish species, pristine corals, and reliable manta ray encounters. Best from October to April.

Best for: Experienced divers seeking world-class reefs and big marine life.

Komodo National Park

Famous for manta rays, healthy reefs, and the legendary Komodo dragons on land. Strong currents bring nutrient-rich water and spectacular marine life.

Best for: Intermediate to advanced divers, underwater photographers.

Tulamben, Bali

The USAT Liberty wreck and incredible muck diving. Easy shore access makes this perfect for beginners and macro photography enthusiasts.

Best for: All levels, especially macro photographers and those wanting easy diving.

Planning Your Trip

Best Time to Visit

  • Raja Ampat: October–April (calmest seas, manta season peaks Feb–Mar)
  • Komodo: April–November (dry season, best visibility)
  • Bali: April–November (dry season)

Liveaboard vs Resort

Both are excellent options in Indonesia. Liveaboards allow you to cover more ground and reach remote sites. Resorts offer more relaxation between dives.

Getting There

Most international flights arrive in Bali (DPS) or Jakarta (CGK). Raja Ampat requires connecting flights to Sorong.
