Indonesia is one of the world’s most rewarding scuba diving destinations. Sitting at the heart of the Coral Triangle, the country offers extraordinary marine biodiversity, dramatic underwater landscapes, and dive sites suited to every experience level. From remote coral gardens to fast-moving channels filled with pelagic life, diving in Indonesia is as varied as the islands themselves.
Below are the standout diving destinations across the archipelago, each offering something distinct beneath the surface.
Raja Ampat
Raja Ampat is widely regarded as Indonesia’s premier diving destination. Located in West Papua, this remote archipelago lies at the center of the Coral Triangle and holds the highest recorded marine biodiversity on Earth. Coral reefs here are dense and vibrant, supporting manta rays, reef sharks, and enormous schools of fish across shallow reefs and deep channels.
Because many dive sites are far from populated islands, Raja Ampat diving liveaboard trips are a common choice, offering access to untouched reefs and rarely visited locations.

Komodo National Park
Komodo National Park delivers some of the most intense and exhilarating diving in Indonesia. Strong tidal currents move through narrow channels and seamounts, creating nutrient-rich conditions that attract manta rays, sharks, and other large pelagic species.
Komodo National Park diving is best suited to confident divers who enjoy fast drift dives and constantly changing conditions. On land, the park is famous for the Komodo dragon habitat, making it one of the few places where world-class diving and iconic wildlife coexist.
