Eight nights is the length at which Raja Ampat stops being a highlights reel. THE ORACLE's longer loop runs south from Sorong first, to the wreck at North Batanta and the maze of lagoons at Misool, then back north through Wayil, Piaynemo and the manta hotspot at Kawe before finishing in the Dampier Strait.
The south is quieter than the north and its reefs are, if anything, richer: Boo Window and Magic Mountain at Misool, the jellyfish lake at Balbulol, soft-coral caves at Farondi. The north gives you the viewpoints. Doing both in one trip means one long night passage and no repeated anchorage.
Six guests and ten crew. Fly into Sorong, board from eight in the morning, and the boat sails the same day.
