Visitors are drawn to the volcanic complex for hiking along trails that provide views of fumaroles, lava flows, and crater rims, as well as opportunities for camping, wildlife viewing, and soaking in natural hot springs. The Antillanca ski resort is located on the slopes of the Cordón Caulle ridge, making the park a year-round outdoor destination. The volcanoes’ ongoing activity adds an element of awe and scientific interest, while the park maintains facilities for visitors to engage with the area's natural beauty safely.
