Reserva Nacional Río los Cipreses
Numerous short and moderate trails lead through thick forests of cypress trees at this 92,000-acre national reserve 50 km (31 miles) east of Rancagua. Some of the trails come to clearings where you are treated to spectacular views of the Andes above. CONAF, the national parks service, has an office here with informative displays and maps. Hiking, swimming, and horseback riding are all available, and you can camp overnight at well-run grounds. Just south of the park is the spot where a plane carrying Uruguayan university students crashed in 1972. The story of the group, some of whom survived three months in a harsh winter by resorting to cannibalism, was told in the book and film Alive.
