Explore beyond the reaches of popular port towns to see a more authentic, undiscovered Indonesia. These remote itineraries go where few passenger ships do, and reap the rewards of their custom yet flexible itineraries and excellent local guides leading the way.

Choose from routes that cruise Sulawesi, the Maluku Islands, the Spice Islands, Raja Ampat and the stretches in between. These are truly the most remote and least-visited parts of the Indonesian archipelago. And a highlight is passage aboard the 24-guest Ombak Putih or 12-guest Katharina. These traditional pinisi-style ships are AdventureSmith favorites for private charter cruises due to their romance, Indonesian culture, rustic charm and superior service. Complimentary onboard snorkeling equipment, kayaks, stand-up paddleboards, fishing gear and tender boats equip guests with daily adventures on every route. Learn a bit more about each one:

On the main 14-day itinerary, travel from the spice port of Ternate to the shipbuilding port of Bitung in North Sulawesi while sailing through the islands that fringe the Molucca Sea. Numerous highlights include remote island cultures, Bajau sea gypsies, birds of paradise and other exotic birdlife, volcanic peaks and ample opportunity for snorkeling on fantastic coral reefs and in lakes filled with freshwater stingless jellyfish. Experience Halmahera, the island where famed naturalist Alfred Russel Wallace developed the idea of natural selection via survival of the fittest, then wrote and sent it on to Charles Darwin.

On the alternative 16-day Corals, Cultures & Dragons sail the length of Sulawesi from Bitung Harbor down to Flores Island. The journey is the reward here as you cruise along and meet fishermen and villagers who only see your ship once every few years. While you won’t have the chance see birds of paradise or Halmahera on this route, you’ll trek to see the rare maleo bird, snorkel with sea turtles and seek out black-crested macaques, with the grand finale of seeing Komodo dragons in Komodo National Park. Another similar southbound route sails from Ternate in the Spice Islands to Flores, also over 16 days with Komodo National Park a final stop.

On the alternative 12-day To the Scents of the Spice Islands itinerary, navigate the Banda Islands and much of the famed region as you sail northbound from Ambon to Ternate. Go in search of famed naturalist Alfred Russel Wallace and his living treasures, taking in firsthand experiences of unique ecology and visiting some of the places that most fascinated Wallace: Ambon, the former capital of the Moluccas; Bacan, where Wallace made some of his greatest zoological discoveries (birds of paradise, the world’s largest bee); Ternate, Wallace’s base for his eastern travels and once the center of the world clove trade; and the mysterious island of Halmahera where Wallace discovered evolution by natural selection.

On select alternative itineraries between Ternate and Sorong, also visit the remote Raja Ampat Islands with their pristine, incredibly diverse coral reefs and up to five species of birds of paradise. Many of these sailings feature special guest hosts who are experts in endangered species and evolutionary biology. Or opt for an East Indies Spice Exploration route cruises from Flores to Ambon, exploring more of the Lesser Sundas than other Spice Islands cruise routes. Each itinerary offers a unique slice of history, along with incredible snorkeling, kayaking and trekking.
