Located in the province of Alajuela, Poas Volcano is one of Costa Rica’s most popular active volcanoes to visit. Because it is only about an hour-and-a-half from San Jose, visiting the volcano and national park make for a great day trip. Standing at almost 8,900 ft above sea level, Volcan Poas National Park is actually home to two craters. The bigger of the two craters measures 1.5 kilometers in diameter (0.9 miles) and is 300 meters deep (900 feet). At the bottom of this hole, there is a medium sized blue-green lagoon that emits boiling sulphurous gases. The other crater is called Botos Lagoon which contains cold water.
While Poas Volcano is one of the most active volcanoes in Costa Rica, don’t expect to see lava flow. The last major eruption was in 1910. However, you are likely to see steam and gases coming from the crater, and occasional geyser-like eruptions that have reached up to 820 ft.
The main crater is easily accessed from a paved path/road which is about ½ mile from the visitors center. The second crater, Botos Lagoon, is accessible from a trail off to the side which takes about 20-25 minutes to walk.
Birding & Wildlife Watching
Surrounding the craters, the park is full of dense vegetation and small wildlife, including birds, coyotes, squirrels, rabbits, snakes and frogs. Larger mammals are not typically found here due to the higher elevation.
Best Time to Visit
The best time to visit the volcano is in the early morning before the clouds roll in and cover it (usually before 10 am is best). Getting to the park is a beautiful, scenic drive, boasting views of rolling coffee plantations and flower farms. Because of the higher elevation, it can get quite chilly and damp, so a light jacket or rain parka and appropriate walking/hiking shoes are recommended.
Many people enjoy visiting Poas Volcano in the morning, and on the way down stopping at La Paz Waterfall Gardens. The combination of the two attractions makes for a wonderful day without having to travel far from San Jose.
