Overview of Irazú Volcano National Park

Irazú Volcano National Park safeguards the towering Irazú Volcano, which, at 3,432 meters above sea level, is the tallest volcano in Costa Rica. Established in 1955, Irazú Volcano National Park has since been expanded to cover approximately 2,000 hectares, protecting the volcano and the surrounding landscapes. This active volcano has a long and dramatic history of eruptions, with the first recorded activity dating back to 1723.

There have also been major eruptive periods occurring between 1917 and 1994, including explosions of ash and steam, mudflows, and seismic rumblings. Today, the volcano exhibits minor fumarolic activity, releasing gases and occasional ash. It is considered level 1 out of 5 in terms of volcanic risk, making it safe for visitors.

The park features a range of fascinating geological sites, including the Hermosa Beach, Principal, and Diego de la Haya craters. One of the park’s highlights is the Sapper formation, the highest point in the volcanic massif. From here, it is possible to glimpse both the Caribbean and Pacific coasts on clear days.
