The legendary Molucca Sea, known for its precious spices that attracted early traders from Europe, is not only one of Indonesia's most interesting and beautiful areas. It also has the largest density of active volcanoes of any region in Indonesia, thanks to a very complex and unique tectonic setting.
Two active subduction zones to the west and east have consumed a small oceanic microplate, the Molucca Sea plate, producing two active volcanic arcs in North Sulawesi and in Halmahera. On this tour we visit no less than 5 of the most active volcanoes in the world, two of which - Dukono and Ibu - have been in near permanent activity for years while the others, Lokon, Soputan and Karangetang erupt frequently.
Each of the volcanoes is completely different in character and provides a great adventure to explore. The tour for a small group is an immersion into colorful cultures and an intense meeting with its very friendly people. Last but not least, the delicious, spicy cuisine of the region will enchant you.
  • All major active volcanoes of North Sulawesi: Lokon, Soputan, Karangetang
  • Ibu and Dukono on Halmahera: two of the world's most active volcanoes
  • Ternate with its colonial charm and gemstone trade
  • Delicious food
  • Very small group
