Bida Nai

The smaller of the twin Bida islets, with a shallower reef profile that makes it ideal for less experienced divers and night dives. Hard coral coverage on the north face is exceptional — fields of staghorn and brain coral that survived the 2010 bleaching event better than most Andaman sites. Titan triggerfish are territorial in the shallows; blue-spotted stingrays cruise the sandy channels between coral heads.
