Volcanoes & Spices This 17-days adventurous expedition is one of our most exciting volcano tours! Visit Halmahera, North Sulawesi and the Sangihe Islands with some of Indonesia's most active volcanoes, including Dukono, Ibu, Lokon, Soputan and Karangetang.
Volcano Special Tours We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
