Irazu Volcano National Park: Unveiling the Majesty of Costa Rica's Highest Volcano

A Volcanic Legacy

Rising to a formidable elevation of 11,260 feet (3,432 meters) above sea level, it commands attention and awe from all who venture here.

The Volcano's Legacy

Irazu has left a profound impact on the landscape, shaping the surrounding terrain with its eruptions over millennia. The most recent major eruption, which began in 1963 and lasted for more than two years, altered the landscape dramatically, leaving behind a lunar-like landscape of ash and rock. Today, remnants of this eruption serve as a hauntingly beautiful reminder of the Earth's incredible power.
