Mount Lokon

Mount Lokon is an active stratovolcano in Tomohon Utara, Tomohon City, North Sulawesi, Indonesia, forming a twin volcano system with Mount Empung. Rising to about 1,580 meters above sea level, it lies on the Pacific Ring of Fire and is one of Sulawesi's most active volcanoes. Notable for its active crater, sulfur fumaroles and panoramic views over Tomohon, Manado and surrounding highlands, it is a popular hiking and nature destination when volcanic activity permits.

Visitors can expect a moderately strenuous hike through tropical vegetation and volcanic terrain to the crater rim of an active volcano. The trail from Kakaskasen village leads to a barren crater area with sulfur vents, rocky slopes and expansive views over Tomohon, Lake Tondano and the Manado coastline on clear days. There are no permanent structures at the summit; the experience is focused on nature viewing, photography and observing volcanic landscape. A local guide is commonly used and access depends on current volcanic activity status.

Mount Lokon is one of the most active volcanoes in North Sulawesi, with documented eruptions in the 20th and 21st centuries including significant activity in 1991, 2011-2012 and 2015. It forms the Lokon-Empung twin volcanic complex and is monitored by the Indonesian Center for Volcanology and Geological Hazard Mitigation (PVMBG) due to its frequent phreatic and explosive eruptions.
