You cannot claim to have visited Raja Ampat if you have not seen the passage.
“The passage” is what separates Gam Island from Waigeo, it is no more that 20m at the narrowest and 300m long.
The current of the passage is affected by the tide of the ocean; water is squeezed through the passage from the Pacific Ocean on a rising tide creating very strong currents. Because of these strong currents it attracts a lot of interesting fish life. The coral life is also spectacular – just 2 meters of water. Planning a kayak trip through the passage is vital due to the currents and a tide chart should be at hand when planning the passage
