What to expect from Poás Volcano National Park

Just 50 kilometers from the city of San Jose, deep in the Central Valley region, you’ll find the AMAZING LANDSCAPE of Costa Rica’s Poás Volcano, which is the main attraction inside the Poas Volcano National Park.


FUN FACT: Thanks to effective management and safety protocols, the Poas Volcano has successfully reopened to visitors, even amidst increased volcanic activity (we’ll cover this below).


How should you imagine the volcano? First of all, Costa Rica’s Poás Volcano stands tall at an elevation of 8,885 feet (2,708 meters) above sea level. BUT even more special are the crater lakes!


The Two Crater Lakes

The Poas volcano, with its two craters, is a powerful symbol of the GEOTHERMAL FORCES that formed Costa Rica.


The park’s main attraction, the Laguna Caliente, or HOT LAGOON, is an active crater filled with acidic and toxic water (don’t even think about swimming in there). However, the crater also provides a unique opportunity to observe the ACID RAIN phenomenona.


INSIDER FACT: Since 1989, the volcano has naturally increased its gas emissions so much that it is causing acid rain phenomena that have already damaged nature in some sectors of the park and surrounding agricultural plantations in the area.

Lake Botos, an EXTINCT crater lake, is a peaceful contrast to Laguna Caliente’s volatile state. The Botos Lake is cold but has see-through water and is surrounded by a cloud forest within the Poás Volcano National Park.


These two crater lakes, each with its own distinct character and deep history, make you feel very much alive and respect the power of Mother Nature. We felt fortunate to see the two crater lakes.


Flora and Fauna

The Poás Volcano National Park spans nearly 15,000 acres. Some locals even say the national park is a treasure trove of biodiversity and birds. With the help of park rangers, birdwatchers will be delighted to spot some of the park’s 80 (!) bird species, including the resplendent quetzal, hummingbirds, toucans, sooty robins, and black guans.


The park’s diverse flora, ranging from small cypress and tucuico to small cedar, makes it one of the most diverse ecological places on the planet.

Planning Your Visit to Poas Volcano

A well-thought-out plan will help you maximize your Poas Volcano experience. We’re here to provide you with one, so you don’t have to worry about a thing.


Ideal Visiting Time

The park opens its doors at 8 AM, and we (definitely) recommend an early morning visit to increase your chances of clear views (and fewer people). Yet, you should be ready for cold, cloudy, and windy weather. So definitely take some warm clothes with you. Don’t feel sad when there are clouds; the Poas Volcano has a microclimate, so half an hour later the skies might be blue again!


Also, keep in mind that the park may temporarily close due to increased volcanic activity or eruptions. In such cases, you can either reschedule your visit or request a refund (we’ll go over this below).

Weather Considerations

Poas Volcano is known for its weather conditions, which include:

  • During the DRY season, temperatures at the volcano can reach up to the mid-70s F (24 Celsius)
  • In the RAINY season, temperatures can drop to the low 60s F (16 Celsius) or colder.


Furthermore, clouds typically start to form over the top of Poas Volcano every day, beginning at 9 a.m., potentially hindering visibility (so visit at 8 a.m. when the park opens). Therefore, checking live weather reports from nearby stations, which heavily influence the cloud cover around the crater, is recommended before your visit.

Safety Measures

Your safety is important during your visit to Poas Volcano National Park. Here are the safety precautions to keep in mind:

  • Upon arrival in the national park, you’ll be required to wear hard hats for protection.
  • View a short safety video that educates about the volcano and safety precautions.
  • The park uses a color-coded flag system to indicate current safety levels.
    • A green flag indicates normal conditions, meaning all activities in the park can proceed as usual.
    • A yellow flag signifies that there may be some minor disturbances, so stay alert.
    • Lastly, a red flag is raised when there is significant volcanic activity or other serious risks, often leading to the closure of certain areas or the entire park for safety reasons.
  • Concrete structures near the crater serve as shelters in an emergency.
  • Adhere to park ranger instructions and avoid illegal or restricted areas. The park rangers can answer all your questions and ensure your safety.


Due to potential risks such as volcanic gases, ash fall, and falling rocks, the recommended VIEWING TIME at the active crater viewpoint is only 10 minutes.


In cases of high volcanic activity or dangerous gas levels, the park closes the viewpoint or the entire park, in which case you can reschedule your visit or request a refund by emailing the park office.

Organized tours offer various options, from all-inclusive packages that span over a week to day trips that include visits to this and other national parks, waterfalls, and volcanoes. We love booking our day trips with Get Your Guide, as they offer qualitative and good value-for-money visits!

Experiencing Poas Volcano: Trails and Observation Points

Poas Volcano National Park is not just about the stunning landscapes and unique geothermal features; it’s also about the journey. As part of the national park system, the park offers many trails and observation points.


The main accessibility feature is a paved road that leads almost to the crater’s edge and is wheelchair-friendly, allowing you to approach within 300 feet (around 90 meters) of the crater’s rim. There’s also a 600-meter asphalted trail leading to the active crater observation point that is accessible for wheelchairs.


Main Crater Observation Point

The main crater observation point offers a close-up view of the active crater. From this platform, you can look into one of the largest active craters in the world. However, given the high altitude of Poas Volcano, weather conditions can quickly change, which can include cold and wet conditions affecting visibility. To ensure safety and accurate monitoring, a volcanological and seismological observatory is nearby monitoring all the volcanic activity.


INSIDER TIP: If clouds obscure the crater view, you can take a short stroll down nearby trails in the cloud forest and return later to the observation deck for another chance to see the sulfuric pool, smoke, and geysers.


Laguna Botos Trail

Botos Lagoon

For those seeking a slightly more adventurous experience, the Laguna Botos trail is a must-try. Considered to have a medium level of difficulty, the trail spans 2.1 miles (3.4 kilometers). The main viewpoint of the inactive crater lake can be reached after a 0.5-mile (800-meter) hike from the start of the trail, which takes visitors about 20 minutes to arrive at the viewpoint. DOWNLOAD THE TRAIL FOR FREE HERE.


To complete the entire Laguna Botos trail, including the return journey, you should allot approximately 40 minutes. This hike not only offers spectacular views but also encounters with wildlife, such as various bird species and chipmunks, creating an enchanted feeling.


What to Pack for Your Visit

You should be prepared for your visit to Poas Volcano in the mountains. Here are some items to bring with you:

  • A sweater or jacket, as the volcano’s higher elevation can be chilly
  • Closed-toed shoes and long pants for protection against the terrain and weather conditions
  • Dressing in layers to adapt to fluctuating temperatures at elevated heights


Some other essential items to pack for your visit to Poas Volcano include:

  • A rain jacket or poncho, as the weather can be unpredictable
  • A camera to capture your memories

Just a short drive from Poas Volcano, you’ll also find the city of Alajuela. Known as the ‘City of Mangoes‘, Alajuela is the second-largest city in Costa Rica and is rich in history and culture. It’s the birthplace of the country’s national hero, Juan Santamaria, and home to his museum. The city’s central park, Parque Central, is a lively spot where locals gather, and the nearby Alajuela Cathedral is a must-see. Alajuela is also home to a variety of markets, offering a plethora of local fruits, vegetables, and crafts.

Animal enthusiasts can visit the Territorio de Zaguates, a large no-kill shelter for around 900 dogs, offering a unique opportunity to interact with animals and support the shelter.


If you want to extend your Costa Rican adventure, a visit to Bajos del Toro is a must.
