Fodor's Expert Review Reserva Nacional Altos de Lircay

With long trails that cut through native oak forests and overlook canyons, mountain lakes, and volcanic cones, the Reserva Nacional Altos de Lircay is, unsurprisingly, quite popular with hikers. To reach the CONAF–administered park, head 66km (41 miles) east of Talca on paved roads that turn to gravel for the final 20km (12 miles). The resort town of Vilches near the park entrance has restaurants and cabins for those who don't want to camp. The park is snowed over--and largely inaccessible--July through September.
