Sipiso-piso Waterfall
This waterfal is definitely majestic. It flows out from a small ravine, which makes it took like it flows out directly from a hole approximately 120 metres up on the vertical mountainside. The stream flows to Lake Toba. There is a viewpoint 150 metres off the road and 6 km before Tongging coming from Merek. Another more adventurous way to see the fall is to trek along the river from Tongging until the fall. It is possible to bathe below the fall. The water is clean and nice, but has passed through villages before the fall so do not drink it. From here are stairs leading up to the viewpoint. This waterfall of course has a legend, it is a long story, but in short it all happened when a dragon in the river tried to make his way to Lake Toba. During his attempts he got into a big fight with the creature that ruled in the lake. Their fight was si violent that a ravine was created. This is where the Sipiso-piso falls down today.

Pansur Napitu
Pansur Napitu is an approximately 30 m high waterfall in seven steps. According to locals, the rocks next to the fall can breathe and sometimes let out sounds. The area of the fall is considered eerie.
