Yanachaga–Chemillén National Park lies more or less right on the boundary between the Andean and Amazonian "halves" of Peru. The park is situated in the Pasco Region, which lies more or less in the geographic center of the country. In this drone video by Niels Ahmes, you'll get to see an epic ATV trek into the park from the launching point of Oxapampa. The town lies on the eastern side of the Pasco region. The terrain here is referred to as the Selva Alta, which translates roughly to "High Jungle".
