Sollipulli is a unique ice-filled caldera volcano located in the heart of the Andes, straddling the border between Chile and Argentina. Unlike its more famous neighbors, Sollipulli features a massive 4-kilometer-wide ice-filled crater that contains approximately 15 cubic kilometers of glacial ice. This extraordinary combination of volcanic and glacial features makes it one of the most distinctive volcanoes in the region.
The volcano’s remote location and challenging access make it a destination for serious adventurers and scientists studying volcanic-glacial interactions. Its last major eruption occurred around 1240 CE, though the volcano remains potentially active beneath its thick ice cap. The surrounding wilderness offers pristine trekking opportunities through ancient Araucaria forests and alpine meadows, rewarding visitors with breathtaking views of this hidden gem of the Araucanía region.
