Deep Turbo
Sea mounds rising from sand at 30 m to about 18 m

A deep site off the northeast of Gili Trawangan where large sea mounds rise out of a sandy bottom at 30 m, the biggest of them topping out around 18 m. The mounds carry overhangs and outcrops rather than flat coral, and the dive is spent circling and crossing between them. It is the deeper end of what the Gilis offer.

The dive
The descent goes down to sand at 30 m, and the shape of the site becomes clear from there: large sea mounds standing up out of the flat bottom, ranging in size, the biggest rising to about 18 m. Dropping in deep and looking up at them is the reason to dive this way round rather than working down from the top. Bottom time at 30 m is short, so the plan is usually to reach the sand, orient on the nearest mound and start climbing.
Each mound carries overhangs and outcrops rather than an even coral surface, so the swim around one is a series of ledges and cut-backs to look under. Rising as you circle keeps the profile going the right way, and the tops at around 18 m are where most of the dive gets spent. Cross to a second mound if gas allows, then ascend off the top of it into open water for the safety stop with the boat following your bubbles.
