Batu Niti

Fine sand and rock past 30 metres, dived for the small stuff

Batu Niti is a critter site in the Seraya stretch of the Tulamben coast: rocky shallows leading into a gentle slope of fine sand that continues down past 30 metres. Sand and rock are the defining features, but the slope also carries small corals, wire corals and hydroids, and the encounters listed for it are boxer crabs, frogfish, ghost pipefish, nudibranchs and octopus.

The dive

The site starts in rocky shallows and then becomes a gentle slope of fine sand that continues down past 30 metres. That transition is the dive: the rocks give shape near the surface, the sand takes over below, and there is no wall or structure to navigate around, so you pick a depth band and work along it rather than swimming a circuit.

Fine sand and rock are the most distinguishing feature, but the slope is also home to plenty of small corals, wire corals and hydroids, and those are what to search. Boxer crabs, frogfish, ghost pipefish, nudibranchs and long-arm octopus head the list of encounters here, with eels, groupers and angelfish alongside them, so the pace is slow and close to the bottom and buoyancy matters more than range.

Know before you go

  • The slope keeps going past 30 metres with nothing to mark the depth, so watch the gauge rather than the sand and set a turn depth before you drop in.
