Located in Central Costa Rica, Irazú is an active volcano. Its maximum elevation is 11260 feet (3432 m) above sea level making it the highest volcano in Costa Rica. It used to have a spectacularly blue lake at the bottom of its crater, but an earthquake several years ago reorganized the mountain's plumbing and it drained away. The National Park is very accessible, and it is a beautiful drive . The weather can be changeable, so be prepared for a bit of everything.
