About This Trip

  • Our unique itinerary will take you to remote and spectacular coral reefs adjacent to Raja Ampat.
  • Travel aboard a boutique liveaboard experience in a small group with full service staff.
  • Make stops on land for birding and primate viewing.

This is a unique and rarely offered itinerary in the biogeographic region of Wallacea, from the “Spice Island” of Halmahera to Sulawesi. Adjacent to Raja Ampat, Indonesia but with much fewer visitors, Halmahera offers some of the best hard coral gardens in all of Indonesia. In Sulawesi we will encounter unique macro critters and visit the Tangkoko Nature Reserve, a haven for endemic species.

Coral reefs in this region are largely unexplored by snorkelers, and on this unique liveaboard expedition you will have the chance to be among the first travelers to identify new reef areas. Our snorkeling-focused itinerary will have you in the water 4-5 hours per day as we explore this area's pristine reefs, teeming with large schools of fish.

Above the water, the islands of Sulawesi and Halmahera are also home to unique terrestrial biodiversity. Throughout this expedition we hope to see parrots, hornbills, birds of paradise, and unique mammals of the Tangkoko Forest Reserve. Weather permitting, we will also stop at the Togean Islands and visit the Red Jellyfish Lake.

Conservation Impact

Founded in 1969, Oceanic Society is America’s oldest nonprofit organization dedicated to ocean conservation. As pioneers of “eco travel,” our expeditions have been designed to support our mission. They not only positively impact our travelers, but also the people, places, and wildlife we go to see. A portion of your trip fees for this expedition will support organizations we visit or collaborate with in Indonesia, including Planet Deep, The Coral Triangle Center, and the Misool Foundation. Over the 13 years we have been leading trips in Indonesia, we have supported groups working on coral reef restoration, marine protected area design and management, plastic pollution solutions, and shark conservation. Over the years, we have provided thousands of dollars in park fees that support the protection of marine areas like Raja Ampat and Komodo National Park.
