The Amazon Of The Seas: Underwater Indonesia

With more than 1,300 species of fish, six of the world's seven species of sea turtles, and at least 450 species of reef-building coral, bioligists have good reason to dub the Raja Ampat (or Four Kings) Archipelago the "Amazon of the Seas."

In 2013, Asia Transpacific Journeys is pioneering a snorkeling expedition to this isolated corner of ocean, led by marine biologist guides, and Seattle-based outfitter SeaTrek Sailing Adventures provides trips in the region aboard its traditional ironwood Phinisi schooners.
