Raja Ampat Manta Ray Season — When & Where to See Mantas
Raja Ampat’s manta ray season draws divers and snorkelers from around the world to witness one of nature’s most majestic spectacles. The region hosts both reef mantas (Mobula alfredi) and the giant oceanic manta ray (Mobula birostris), with encounters possible year-round but peaking during specific months depending on location.
Peak Manta Season by Region
Dampier Strait (North): November to April — the primary manta season. Nutrient-rich waters attract large aggregations to cleaning stations like Manta Sandy and Arborek Jetty. This is when most divers plan their trips.
Misool (South): June to September — southern Raja Ampat sees manta activity during the opposite season, meaning dedicated manta seekers can find encounters year-round by choosing the right itinerary.
Year-round sightings: While peak months offer the highest probability, mantas are resident in Raja Ampat. Even outside peak season, encounters are common at established cleaning stations.
Best Dive Sites for Manta Rays
Manta Sandy — the most reliable manta cleaning station, with encounters on 90%+ of dives during peak season. Shallow depth (12-16m) makes it accessible to all certification levels.
Arborek Jetty — mantas cruise past snorkelers at this village pier. No diving required.
Blue Magic — pelagic encounters including mantas, sharks, and schools of barracuda.
Cape Kri — world fish count record holder where mantas are regular visitors.
