17 days volcano trekking
: This is one of our most exciting volcano tours! Halmahera, North Sulawesi and the Sangihe Islands are not only very scenic and interesting as well as nearly unspoiled by tourism, but also home to some of the country's most active (and often erupting) volcanoes, inclduing Dukono, Ibu, Lokon, Soputan and Karangetang.
