This mountain is just across from Mt. Kerinci, but is a much easier (3-4 hour) hike. At about 2,000 meters you will find a large, pristine crater lake surrounded by virgin rainforest and seven mountain peaks that rise for another 800 meters or so. It’s the highest volcanic crater lake in SE Asia. At the top, if your guide has arranged for it ahead of time, you can rent some of the local fisherman’s dugout canoes and paddle across the lake to set up camp.
