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 miles) from the village of Yanahuanca to the village of Huarautambo, where pre-Inca ruins dot the rugged terrain. Continue along the 150-km (93-mile) Inca track and you'll pass La Union, San Marcos, Huari, Llamellin, and San Luis.
