After founding the Irazú Volcano National Park in 1955, the nature reserve was extended to a size of 4,942 acres (2,000 hectares) in 1988. The last volcanic eruption that covered San José and Cartago with volcanic ash and dust took place in 1963.
The national park owes its name to an Indian tribe named Iztarú, who lived on the huts of the volcano. In their native language, Iztarú meant “quake and thunder hill”. In the course of time, the name changed through the verbal communication to Irazú.


Due to its geographical location in the central mountain chain and its altitude, the Irazú volcano is a strategically valuable location for national telecommunication companies.

How to get there

The Irazú volcano is about 54 km from San José and you can reach it via two different ways. You drive either via Cartago or via Rancho Redondo. Afterwards you pass Tierra Blanca and San Juan de Chicuá and follow the street until you get to the entrance of the volcano. The second route leads through beautiful rural landscapes, but the condition of the roads is unfortunately not optimal and it is recommended a 4×4 vehicle. Both routes last approximately 1.5 hours.

To get to Prusia, turn left towards Sanatorio Durán, also an interesting place to visit and explore, 2 km after Tierra Blanca and follow the road until you get to the entrance. For this route we also recommend a SUV.

Opening hours

The Irazú Volcano National Park is opened form 8 am to 3:30 pm, 7 days a week, including national holidays.
