Discover more about Parque Nacional Volcán Poás

Poás Volcano National Park, established in 1971, is a testament to Costa Rica's geothermal wonders and natural beauty. Situated in the mountainous forests of the Central Volcanic Mountain Range, the park spans approximately 6,506 hectares (16,000 acres) and is easily accessible from major cities, making it a popular destination for tourists. The park's main attraction is the Poás Volcano, a complex stratovolcano boasting one of the largest active craters in the world, measuring roughly 1.6 kilometers (1 mile) across and 320 meters (1,050 feet) deep. The main crater features a hot, acidic lake, with temperatures ranging from 20 to 50°C. Visitors can often witness smoke and steam rising from fumaroles within the crater, a powerful reminder of the volcano's activity. Beyond the main crater, the park features other points of interest. The Botos Lagoon, a cold-water lake residing in an extinct crater, can be reached via a 1.4 km (0.87 miles) trail through a miniature cloud forest. The Von Frantzius cone, located north of the active crater, presents a unique horseshoe shape and is partially covered in vegetation. The park is also home to diverse wildlife, including various bird species such as the mountain tanager, large-footed finch, and black-billed nightingale-thrush. The park has been awarded the Certification of Sustainable Tourism (CST) at the Elite level, recognizing its commitment to environmental and cultural preservation. Note that as of July 2025, Poás Volcano is currently closed due to increased volcanic activity.
