Given the remoteness and low population density of the Anambas Archipelago, the aquatic environment here is virtually pristine, with extensive fields of thriving coral gardens, complete with abundant flora and fauna. Throw in some of the clearest water you'll encounter anywhere and it's clear that Anambas is nothing short of a scuba diving paradise.
Best of all, the area is quite sheltered from the N.E. monsoon, allowing pretty much year-round scuba diving. In fact, diving in Anambas will almost guarantee you see all kinds of amazing sea life, including superb macro, as well as rays, barracudas, moray eels, sharks and turtles. And whilst not a regular sight per se, don't be surprised if you come across a whale shark too, because they've been known to use these waters for their migrations.
Some other go-to locations of choice are Igara Wreck, Seven Skies, Pulau Damar, Pulau Tokong Malang Biru, Pulau Repong and Batu Kataoka.
