Beyond Raja Ampat: 8 Lesser-Known Dive Destinations in Indonesia

Why Go Beyond Raja Ampat?

Raja Ampat is undeniably a diving mecca, attracting thousands of divers every year. But with that popularity comes crowded dive sites, stricter access regulations, and rising prices.

For some divers, the allure of Raja Ampat has faded, replaced by the search for solitude, challenge, and a deeper connection with nature.

Indonesia, however, still holds a wealth of undiscovered and less-visited dive regions that offer diverse marine life, untouched coral reefs, and the thrill of exploration.

Whether it’s hammerhead sharks in the Banda Sea or whale sharks in Cenderawasih Bay, these hidden destinations offer opportunities to experience pristine underwater environments via liveaboard adventures with Uncharted Cruises.
