Kabui Bay separates Gam and Waigeo islands. Here the rainforest meets the reef in a labyrinth of limestone islets teeming with wildlife and bird of paradise. Kabui bay promises spectacular seascapes, especially across a narrow strait that is called The Passage, which opens a gateway to the northern islands of Raja Ampat. The passage is a narrow river-like strait where the blue mangroves and rainforest meets the reef in a maze of limestone cliffs. By the entrance to The Passage, there is a viewpoint that you should visit. After a short hike, a panoramic view of Kabui Bay’s karst islands is breathtaking.The highlight iscalled Batu Pensil, a pencil-like karst jutting out of the water in the middle of the bay.
