Along the road to Harau Valley is a lovely countryside. Steep granite walls shelter the fertile valley. A waterfall, 150 meters high falls into a basin. The Harau Valley is a nature and wildlife reserve, where tapir, siamangs, boars, wild goats and tigers still roam. The Harau Valley is 15 km from Payakumbuh.
