Trip details →These aren't ordinary dive trips. Every departure is led by a working MMF scientist, with a series of evening presentations on the animals, the research and the threats they face — and guests are shown how to take photographs that contribute to the global photo-identification databases our research depends on. MMF is a registered 501(c)(3) non-profit, and 100% of the profit from every expedition supports MMF's research, education, and conservation work.
Tell us which trips you're interested in and your group size — the trips team will come back with availability, pricing, and everything you need to decide. Spaces are limited; enquiring is not a commitment. Back-to-back combinations (Alor–Ambon + Ambon–Raja Ampat, or both Raja Ampat sailings) are very possible.
Our partner operators run their own expeditions hosted by MMF scientists — book directly with the operator.
Ten days through Raja Ampat — more than 600 nautical miles, with both manta species. Includes accommodation, meals, guided dives, transfers, and park fees. Trip one (30 Nov–9 Dec) is sold out.
