The spot to explore covers a 150 to 200 meters-wide area between the beach and the reef drop-off. At this point, starting from the beach, you will cross a few dozen yards of sandy areas and seagrass (↕0.5-2m), then a sea bed covered with coral (↕2-3m) as far as the reef drop-off (+6m).

This spot is certainly the best one in the Gilis to swim with green sea turtles, which uses to feed and rest on the sea grass beds, sometimes a few meters only from the beach. You can also meet hawksbill sea turtles on the coral areas along the drop-off, especially at high tide.

Surgeonfish and parrotfish at Gili Trawangan

On Gili Trawangan, like on Gili Meno and Gili Air, the turtles have been long used to human presence and can be easily approached and observed. Avoid disturbing the turtles, which come to the area to feed and rest: don’t chase after them, don’t touch them, and leave them enough room when they come up to the surface to breathe.

While swimming with turtles is the main attraction on the island, the other beauties of the area should not be overlooked. Along a strip of ten or so meters along the reef drop-off, the seabed is full of marine life. The reef is covered with soft and hard corals, and plunges abruptly down toward an immaculate sandy seabed. Parrotfish are abundant on the drop-off, as are butterflyfish and surgeonfish, often seen in large schools. You will also come across small groups of Moorish Idols, or sixbar wrasse, which is more shy however.
