About Raja Ampat

Raja Ampat spreads over hundreds of islands and reefs off West Papua, where divers count more coral and fish species than anywhere else on Earth. Liveaboards and homestays on Waigeo, Misool and Arborek reach the sites, and the karst viewpoints and Piaynemo lagoon fill non-diving days. October to April is the calmer season for crossings; July and August bring wind and plankton-rich water, and conditions vary by site.
