With its location just above the San Jose metropolitan area, a visit to Poas National Park is a popular day activity. Locals and tourists both like to visit the volcano. However, the volcano is active and during the months of March and April 2025, we definitely notice it.
Parque Nacional Volcán Poás was created in 1955 and what is special is that this volcano has one of the largest craters in the world. Another special fact is that this volcano is active. It rumbles and bubbles with regularity. After the eruption in 2017, the national park was closed until 2018. Then the volcano also erupted briefly twice again in 2019. And now, in 2025, it will hit again: the Poas volcano is making itself heard!
The activity of the volcano is always monitored. This is done by a research institute of the national university: OVSICORI-UNA. If you would stand near the crater, you can see by a kind of traffic light system that the amount of volcanic gas is being monitored. Through webcams you can watch along as an outsider at the volcanoes. At least when the view is not blocked by clouds.
Due to increased activity, the Poas Volcano National Park is closed again on March 26, 2025. The eruptions increase and on April 23, 2025, the National Emergency Committee (CNE) issues a red alert. Ash clouds reach as high as 4,500 meters. Officials see a continued increase in activity.
Ash precipitation and the smell of sulfur have been reported in several areas, especially near Grecia and Sarchí. Volcanic activity is also affecting crops, pastures and livestock in surrounding areas.
For now, there are no indications that air traffic will be inconvenienced by this active volcano, nor have any roads been closed.
Due to the increased activity, there are several levels of warning:
🔴 Red alert – Poas National Park is temporarily closed to visitors.
🟠 Orange alert – the villages of Grecia and Sarchí are under increased vigilance.
🟡 Yellow alert level – Applies to Alajuela, Poas, Naranjo, Río Cuarto and Zarcero.
Official recommendations:
– Avoid high-risk areas and strictly follow directions from local authorities.
– Consult reliable information sources such as OVSICORI, RSN and CNE for current updates.
– Protect your respiratory tract in the presence of ash in the air.
– Report gas or ash sightings to local emergency responders.
