Irazú Volcano, Active stratovolcano in Cordillera Central, Costa Rica
Irazú Volcano is an active stratovolcano in central Costa Rica that reaches 3,432 meters at its summit. The mountain has five craters, with the largest containing a green lake that shifts in size with water levels, while steam vents remain active across the crater walls.
The volcano's first recorded eruption occurred in 1723. A major eruption from 1963 to 1965 sent ash across the country to San José and damaged agricultural areas around Cartago.
The name comes from indigenous languages, where 'Irazú' refers to thunder and pointed peaks. Local people call it 'El Coloso' for its powerful presence, and many stories passed down through generations speak of the forces hidden beneath the earth.
A paved road leads directly to the summit where walking paths circle the main crater zone. Weather shifts rapidly at this elevation, so bring warm layers and wind-resistant clothing regardless of conditions at lower altitudes.
On clear days, both the Atlantic and Pacific oceans are visible from the summit across the country. This simultaneous view of both coasts makes for a rare and memorable moment for visitors.
