Raja Ampat Aggressor

Routes: Round trips out of Sorong through the Dampier Strait, Penemu and Misool, with some seasons adding crossings toward the Banda Sea. Charters follow the Aggressor pattern of up to five dives a day where park rules allow.

Character: Reef biodiversity, mantas and small-boat access to remote sites

Prices: Broadly $4,000-5,500 per person for a week plus park and port fees. Itineraries, pricing and even the vessel assigned to a route change often; confirm every detail with the operator before booking.

Departures: Embarks in Sorong, West Papua, reached via Jakarta or Makassar.
