Sierra Nevada is a volcanic complex located immediately northwest of Llaima Volcano within Conguillio National Park. At 2,554 meters, this glacier-covered volcano features multiple overlapping cones and craters formed over thousands of years of volcanic activity. Its proximity to Llaima creates a dramatic landscape of contrasting volcanic forms.
The volcano last erupted in 1979 with a relatively small explosion, but it remains monitored due to its ongoing geothermal activity. The Sierra Nevada massif is popular with backcountry skiers who appreciate its reliable snow conditions and dramatic volcanic terrain. Summer visitors can explore the surrounding ancient Araucaria forests and witness the stark beauty of recent lava flows that contrast with lush vegetation.
