The landscape panorama, on the road to the village of Haranggaol, Simalungun, shows a Caldera wall consisting of the YTT sediment sequence, MTT, OTT.
Here you will be treated to views of the city of Haranggaol which is at the bottom of the road you pass (you will pass the road along the descending hill), just on the edge of Lake Toba. The scenery of the hills & farms of local residents add to the unforgettable beautiful atmosphere.
