Mount Leuser, Aceh
Hiking this mountain is made difficult by the complicated and unpredictable land—dense untouched jungles, rushing rivers, steep rocks. But the real danger and challenge lies in the wildlife. Even if you stay right on track, there are real possibilities of encountering snakes, bears, even tigers. The summit of Mount Leuser can be reached in about two weeks. The mountain is located in a relatively remote area, and to reach the starting point tourists have to switch flights in the country’s Sharia-governed Aceh Province.
