Poás Volcano National Park
Alajuela
Poás Volcano National Park, located in Alajuela Province, Costa Rica, spans approximately 65 square kilometers and is centered around the active Poás Volcano, which rises to 2,700 meters above sea level. Established in 1971, the park is renowned for its large, active main crater measuring about 290 meters wide, which frequently emits geysers and lava activity. The park also includes two other craters: the extinct Von Frantzius crater and the Botos crater, which contains a striking cold, green crater lake approximately 370 meters in diameter. The Botos crater has not erupted for around 7,500 years, and well-marked trails allow visitors to explore these inactive craters when conditions permit. The park is also a haven for wildlife, hosting unique bird species such as the Poás magnolia bird, clay-colored robin, black guan, resplendent quetzal, hummingbirds, tanagers, flycatchers, and toucans. Mammals like coyotes, rabbits, and marmots inhabit the area as well. Due to the volcano's activity, including eruptions and emissions of water vapor and sulfuric acid gases, the park has experienced periodic closures, and visitors are advised to check current conditions before planning a visit. Its combination of volcanic landscapes, crater lakes, and rich biodiversity make Poás Volcano National Park a captivating destination for ecotourism and volcanic study.
