Blue Marlin Dive Komodo is the Labuan Bajo base of the Blue Marlin Dive group, which began on Gili Trawangan in 1990 and is one of the longest-running dive names in Indonesia. The seafront base pairs a dive center with simple sea-view hotel rooms and an open-air restaurant and bar, so divers sleep a few steps from the boat.

Trips run to the Komodo National Park classics: Batu Bolong, Castle Rock and Crystal Rock in the north, Tatawa Kecil, and the manta channel at Makasar Reef. Expect drift diving, since the park's currents power its fish life. With more than 900 Google reviews, this is one of the most-reviewed operators in town.
