description Irazú Volcano fumaroles Overview
The Irazú Volcano fumaroles are geothermal vents located within Irazú, the highest active volcano in Costa Rica. Situated near the main crater, these vents periodically release sulfurous gases and steam, indicating ongoing magmatic activity beneath the stratovolcano. The surrounding crater is also known for its mineral-rich lake, which frequently fluctuates in color and size depending on rainfall and underlying geothermal conditions. The area is monitored by volcanologists and attracts visitors to Irazú Volcano National Park.
