Simon's Reef

Deep reef meeting sand at 30 m off the northern Gilis

Area photo: Magul · CC BY-SA 4.0

A deep reef in the channel north of Gili Meno and Gili Air, where the reef runs out onto a sandy bottom that lies at 30 m and reaches about 35 m at its deepest. It is dived for depth rather than for shallow coral, which keeps bottom time short and the plan simple. Advanced certification and deep experience are what the site asks for.

The dive

The site is reached by boat from the northern Gilis and dived as a straight descent to the deep part of the reef, where it meets sand at 30 m and drops away to about 35 m. Divers go down the reef, level off before the sand and take a bearing before moving off, because the bottom here carries few landmarks and the reef edge is easy to lose. The deepest part of the profile comes first, at the start of the dive.

From there the dive works back up along the reef, trading depth for bottom time as gas and no-decompression limits allow, so most of the dive after the first few minutes is spent well above the sand. Following the reef in one direction keeps the group together and lets the boat track it from the surface. The dive ends with a safety stop in open water above the reef, with the boat picking up bubbles.
