This nature reserve 18km southeast of Pereira protects a 489-hectare area of high biodiversity between 1800m and 2400m. Set on the Río Otún, it boasts more than 200 species of birds and butterflies and two rare species of monkey, among other wildlife. The reserve has several hiking trails along the river and through the forest, although visitors are not permitted to explore on their own. Guided hikes (COP$7500) leave at 9am, 11:30am and 3pm. Unfortunately the Cascada Los Frailes – a towering waterfall tumbling down a plant-covered mountain – remains closed.
You'll pay the admission fee (COP$6000) at the visitor center. If you're just visiting for the day, a package is available for COP$29,000 that includes admission, lunch and a guided hike along one of the trails.
Reservations can be made through the excellent community tourism organization Yarumo Blanco.
