Draped in lenga, ñire and coigue, the 21.5-sq-km Reserva Nacional Coyhaique has small lakes and Cerro Cinchao (1361m). The park is 5km from Coyhaique (about 1½ hours on foot), with views of town and Cerro Mackay's enormous basalt columns in the distance. Take Av General Baquedano north, across the bridge, then go right at the gravel road, a steep climb best accessed by 4WD.
From the park entrance, it's 2.5km to the Casa Bruja sector, where you'll find campsites (CH$5000 per site) with fire pits, hot water, showers and bathrooms. Hike 4km through coigue and lenga forests to Laguna Verde, with picnic sites and camping with basic facilities. Hiking trails also lead to Laguna Los Sapos and Laguna Venus.
