Conguillio National Park is one of Chile’s most spectacular protected areas, centered around the massive Llaima Volcano. The park’s name comes from the Mapudungun word “ko-ngi-lliu,” meaning “water with monkey puzzle nuts,” referring to the ancient Araucaria araucana (monkey puzzle) trees that dominate the landscape. These prehistoric trees, some over 2,000 years old, create an otherworldly atmosphere reminiscent of Jurassic forests.
The park features dramatic volcanic landscapes shaped by Llaima’s frequent eruptions, including vast lava fields, colorful volcanic ash deposits, and pristine lakes formed by ancient lava dams. The Sierra Nevada lagoon and Conguillio Lake offer stunning reflections of the snow-capped volcanoes, creating perfect photography opportunities. Multiple hiking trails range from easy lakeside walks to challenging mountain ascents, all winding through this UNESCO Biosphere Reserve that protects over 60,000 hectares of unique Andean ecosystems.
