Poas Volcano
Costa Rica's most accessible volcano.
Why Visit Poás?
Poás is one of Costa Rica's oldest national parks and, due to its proximity to the capital city of San José, one of the country's most visited. Most people come to Poás to experience an easily accessible, active volcano. The crater is a short walk from the visitor center. The park makes a perfect day trip for nature lovers and anyone interested in getting up close and personal with an active volcano without exerting themselves too much. This part of the Central Valley is fertile with coffee fields and agricultural farms.
Here are some reasons why you should visit the Poás area:
- Volcán Poás National Park: The highlight of this area, Poás National Park, is one of the most visited in Costa Rica, not only for its proximity to the capital. It offers guests a chance to get up close and personal with an active volcano's crater.
- Experience Rural Costa Rica: The drive to Poás from San José takes you through some of the best scenery that rural Costa Rica offers, with coffee plantations, dairy farms, quaint country villages, and more. It's well worth spending a few days pottering around here, experiencing what is, to many, the "real" Costa Rica.
Where to Stay
Most people coming to Poás stay in San José or near the airport. There are, however, a few boutique inns and cute bed and breakfasts here.
Things to Do
Explore the national park and experience the volcano. There are also coffee farms and rural activities to take part in, from horseback riding to hiking.
Poas Volcano: For Adventurous Day-Trips
Located north of San José, in the province of Alajuela, Poas Volcano is one of Costa Rica’s most famous active volcanoes to visit. Because it is only an hour and a half from the capital, visiting this volcano and the national park makes for a great day trip. Standing at almost 8,900 ft above sea level, Volcan Poas National Park is home to three craters. However, most visitors experience only two of them.
The first crater is the main one, called Laguna Caliente (Hot Lagoon). It's one of the largest volcano craters on the planet, measuring almost a mile across its diameter. Visitors can walk right up to the edge here, where a fence protects them from a 900-foot drop to the bottom of the crater, where the hot lagoon lies. This blue-green lake often bubbles and boils and emits sulfurous gasses. This crater is often a visitor's first ever experience of an active volcano. It is easily accessible from a paved pathway from the parking lot and the visitor center about half a mile away.
Poas Volcano is one of the most active volcanoes in Costa Rica, with increased activity noted in recent years. In April 2017, authorities closed the national park for over a year due to volcanic activity, causing a massive smoke plume to rise almost two miles. Now that the park is open again, you will see steam and gasses coming from the crater and occasional geyser-like eruptions.
To the south of the main crater, the second crater is extinct and contains a beautiful lake, Botos Lagoon, surrounded by verdant cloud forests. Visitors can access a viewpoint looking out over this cold water lagoon through a well-kept trail which takes around 25 minutes to walk.
There's also a third crater, called the Von Frantzius crater, which most day-trip visitors won't see. It's a long-extinct crater, accessible only to the fittest and active hikers, rarely visited.
Visitors to Poás can also enjoy a modern visitor center and museum, where they can learn a lot about the park and volcano in particular and volcanic activity in general. However, 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 when visiting this national park.
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 travel to Poás Volcano
The best time to visit Poás is in the early morning before the clouds roll in and cover the crater (usually, before 10 am is best), a widespread occurrence. This early-morning recommendation applies year-round, although you're more likely to see a clear crater during the December to April dry season than any other time. This is because Poás lies above the frost line and is one of the few places in Costa Rica where the temperature can drop below freezing at night.
Weather in Poás
Poás is one of those rare parts of Costa Rica where you can pretty much count on it to be cold, cloudy, and windy all year round. Although, of course, it's less cloudy and windy from December to April, but only marginally so.
Is Poás safe?
As a national park surrounded by rural communities and farms, the Poás area is relatively crime-free. You're extremely unlikely to be a victim outside of the golden rule about never leaving anything in your car. The biggest dangers come from the volcano itself, which is still active. Be aware that some trails in the park are still closed after the 2017 eruptions and that they can close the park at any moment if the volcanic activity gets too hairy. Oh - and don't get lost, either. Stay on the trails.
