Big Fish Country (Maratua Channel)

Maratua's channel is the region's big-animal dive. The schooling barracuda here are reported as one of the larger aggregations in Southeast Asia, though no published count exists. It runs hard, and it is not a site to try current diving for the first time.

Unique features

  • The atoll's single reef channel — chevron barracuda and bigeye trevally school at the mouth
  • Grey reef, whitetip and blacktip sharks; eagle rays and tuna pass through
  • Tidal flow drives everything; the dive is timed to the water, not the schedule
