Valle Yanahuanca

One of the longest surviving stretches of Inca road, the Qhapaq Nan, passes through the massive rocky outcrops and deep meadows of the Valle Yanahuanca. Forested hills threaded by shallow, pebbled rivers lead 4 km (2½ mi) farther to the village of Huarautambo, where pre-Inca ruins are treasures to search for in the rugged terrain. Continue along the 150-km (93-mi) Inca track and you'll pass La Union, San Marcos, Huari, Llamellin, and San Luis.
