Cordillera de Guanacaste is a volcanic mountain range in northern Costa Rica, near the border with Nicaragua.
The mountain range forms part of the southern region of the Continental Divide and extends 70 miles (113 km) northwest–southeast and contains mostly complex stratovolcanoes. It reaches a high point at the dormant Miravalles Volcano at 2,020 m (6,627 ft).
Cordillera de Guanacaste is divided into two sections:
La Cordillera Volcánica: formed by a series of volcanic edifices that begin with the Orosi Volcano and ends with the Arenal Volcano
La Sierra Minera: depressions located between Arenal and Tapezco
Notable peaks within the mountain range include:
- Miravalles Volcano: 2,028 m (6,654 ft)
- Rincón de la Vieja Volcano: 1,916 m (6,286 ft)
- Tenorio Volcano: 1,916 m (6,286 ft)
- Orosí Volcano: 1,659 m (5,443 ft)
- Arenal Volcano: 1,670 m (5,480 ft)
The Arenal Volcano erupted in 1968, covering the area with hot ash. The eruption wiped out two villages while destroying pasture and killing approximately 100,000 head of cattle. The volcano is still active but less threatening today.
Rivers flowing from the range and draining into the Caribbean Sea include the Guacalito and Zapote. Rivers draining into the Pacific Ocean include the Blanco, Tenorio, Martirio, Corobiá and San Lorenzo.
Protected areas located in the mountain range include Guanacaste National Park and Area de Conservación Guanacaste World Heritage Site, inscribed by UNESCO in 1999.
