Monkey Reef

Monkey Reef is a small reef dived straight from the beach: a stony entry gives way to sand, and a small coral block runs down the slope, with the best of the reef on the left-hand side looking out from the beach. Anemonefish, pufferfish, scorpionfish, filefish, triggerfish and turtles are on it, and bigger fish are sometimes seen between 30 and 40 metres.

The dive

The entry is over a stony section of beach and then straight onto sand, which is where the dive settles. A small coral block runs down the slope from there, and the reef is compact rather than sprawling: it is described as a small reef with many fish and nice corals, so the dive is about covering a short stretch thoroughly instead of pushing along the coast.

Turn left from the beach for the best of it. That side holds the better reef, and working it slowly beats covering ground. The slope runs to a maximum of 40 metres and bigger fish are sometimes met between 30 and 40 metres, so the deep end is not empty — but the anemonefish, pufferfish, scorpionfish, filefish, triggerfish and turtles are shallow, and a deep pass costs most of the dive. Plan the turn on gas and come back over the same ground.

Season follows Tulamben: Diveable year-round with modest seasonal shift; April–October dry season typically gives calmer surface conditions.

Know before you go

  • The slope runs to 40 metres, well past a normal recreational profile, so set a depth limit before you enter rather than following the sand down.
