Conditions & tides

Channel site — tidal current funnels through here and can run fast, changing quickly with the tide. It is usually strongest around mid-tide and eases near the slack windows below. Dive with a local operator who knows the timing.

About this site

This site sits in the waters around Gam and Janggelo islands in the Raja Ampat archipelago, off Waigeo Island in West Papua, Indonesia. The area combines mangrove edges with adjacent reef, typical of the sheltered channels between these islands in the region. Divers here have reported a wide range of life along the mangrove-reef interface, including Anna's chromodoris nudibranchs, blue linckia sea stars, broadclub cuttlefish, and tasselled wobbegongs resting on the bottom. Reef manta rays have also been spotted passing through, alongside reef fish such as pastel-green and zigzag wrasse, vagabond butterflyfish, violet soldierfish, and Pacific bullethead parrotfish.
