Cusuco National Park, National park in Cortés, Honduras

Cusuco National Park is a protected area in the Merendón range of northwest Honduras, mostly cloud forest between 1,500 and 2,450 metres above sea level, with a core zone of about 72 km² inside a 222.23 km² buffer zone. Its giant ferns, the park's main attraction, grow over 20 metres tall, with thick fibrous reddish-brown trunks and arching fronds. A wooden signboard at the entrance carries the decree number 87-87.

Cusuco National Park was declared a protected area in 1987 by the Honduran parliament under legislative decree 87-87, the number shown on the wooden sign at the entrance. The park lies in the Sierra del Merendón, mostly cloud forest between 1,500 and 2,450 metres, with a core zone of about 72 km² inside a 222.23 km² buffer zone.

The park's name refers to the cusuco, the local word for the Central American armadillo, an animal associated with this part of the Merendón mountains. The reserve was declared by the Honduran parliament under legislative decree 87-87, the number shown on the wooden sign at the entrance. Visitors today walk trails through cloud forest where the giant ferns, over 20 metres tall, are the main attraction.

The visitor center offers basic lodging options and four marked trails of varying lengths to suit different fitness levels. Visitors should prepare for changing weather conditions, as the mountain elevation brings both rain and cooler temperatures.

The park's dwarf forest, or bosque enano, grows above 2,000 metres and is characterised by Randia brachysiphon. Cusuco is also a Key Biodiversity Area because the ranges of several globally threatened amphibian species overlap there, and jewel scarab beetles live in its forests.
