Itinerary:

Gunung Sinabung is an active volcano located in the Karo Highlands of Northern Sumatra. At 2460m it is the highest of the area and likely the hardest to climb. The peak is significantly harder to climb than nearby Gunung Sibayak which is popular with tourists and locals alike. Compared to Sibayak the forested slopes of Sinabung are more pristine, the summit views more dramatic and the climb more varied. There is only one route to the summit that we know of and everybody takes the path that starts at Lake Kawar to the North of the volcano. The climb involves around 1000m of ascent in a single day and sections of the climb involve scrambling. Typically the roundtrip takes 6-8 hours. The lower portion of the route is through dense forest while the final third involves scrambling up a narrow strip of lava flow which is particularly fun.

This waterfall is formed by a small underground river of the Karo Plateau and flows out into the Lake Toba caldera. You will see an extraordinary view of Lake Toba from the north side.
