About Sumbawa

About Sumbawa Liveaboard Diving

Sumbawa is a large island in Indonesia's West Nusa Tenggara province, nestled between Lombok to the west and Flores and Komodo to the east. Far less visited than its famous neighbors, the island of Sumbawa offers some of Indonesia's most rewarding and uncrowded diving — from whale shark encounters in Saleh Bay to pristine coral gardens surrounding Moyo Island.

A Sumbawa liveaboard trip combines world-class diving with the adventure of exploring one of Indonesia's last true frontiers. Enjoy free unlimited satellite internet and the best mixture of Enriched Air (NITROX) with the latest technology of Bauer PE 320B Membrane system compressor.

Experience

The Sumbawa Diving Experience

Sumbawa diving is an extraordinary blend of big animal encounters and untouched reef exploration. The island sits at a crossroads of ocean currents that funnel nutrients through its bays and channels, creating conditions that attract whale sharks, manta rays, and a wealth of marine life to waters that few divers ever reach.

Sumbawa Whale Shark Encounters

Saleh Bay is one of Indonesia's most reliable locations to see whale sharks. These gentle giants gather around traditional fishing platforms (bagans) from May to October, offering snorkelers and divers unforgettable close encounters in shallow, warm waters.

Moyo Island & Pristine Reefs

Moyo Island is a protected nature reserve off Sumbawa's northern coast. Its reefs are among the most pristine in the region, with exceptional hard coral cover, reef sharks, turtles, and crystal-clear visibility — all without another dive boat in sight.

Gateway to Komodo

Sumbawa's strategic position between Lombok and Komodo makes it an ideal stop on extended liveaboard itineraries. Dive Gili Banta on the border with Komodo National Park for spectacular drift dives with mantas, sharks, and massive schools of fish.
