Discover and enjoy the panoramic view of one of the largest craters of the world located in the heart of Costa Rica, only 37 km north from the city of Alajuela, at an altitude of 2708 meters from sea level.  This volcano is still active, but the eruption of 1910 is most often remembered as spectacular.  This natural wonder has two craters.  The main one measures 1.5 km diameter and has a circular lake of 350 meters in diameter. The other crater has a beautiful lake of 400 meters in diameter.
