Tenorio Volcano National Park (Spanish: Parque Nacional Volcán Tenorio) is a National Park in the northern part of Costa Rica, which forms part of the Arenal Tilaran Conservation Area. The jewel of the National Park is the volcano, from which it receives its name. The Tenorio Volcano was made part of the National Park in 1995 and is located about 26 miles northeast from the town of Fortuna in the Guanacaste Province.
Tenorio Volcano consists of four volcanic peaks and two craters. One of the craters is sometimes referred to as the Montezuma Volcano.Tenorio attains a maximum height of 6,287 feet (1,913 m). The Rio Celeste (Light Blue River) is turned blue due to the emanation of sulphur from the volcano and precipitation of calcium carbonate. Thermal springs and small geysers dot the area as do rivers, waterfalls, lagoons and panoramic views. The upper area of the park is dominated by primary cloud forest, while the lower regions are carpeted with rain forest. The Tapir and the rarely seen Puma reside in the area.
There is a ranger station at the base of the volcano that provides visitors with basic information. The volcano's summit can be reached via the Lago Las Dantas Trail, which winds up the volcano and passes through forested terrain before eventually reaching the peak.
