Home Sipiso-piso Mountain Gunung Sipiso-piso is a mountain standing alone between Merek and Tongging and doesnít go unnoticed. Itís summit is 1.947m above sea level. The slopes are covered with alang-alang grass except for the summit where there is a small patch of forest. There is a narrow surfaced serpentine road partly reclaimed by grass, all the way to the summit. The views are really breathtaking and one should not be afraid of heights. At good weather Pulau Samosir really looks small in comparison to the vastness of Lake Toba. The only sounds one hears are the birdsong and maybe music from an occasional wedding party in some village far below. The road starts 2,5 km from Merek or 7 km from Tongging. It is 3,5 km to the summit.
