The most famous and developed mountain resort south of Santiago is the Nevados de Chillán, an all-season tourist complex which includes one of the largest ski resorts in Chile, 80km east of Chillán, nestled at the foot of the 3122m Volcán Chillán. Formerly known as the Termas de Chillán, it possesses three year-round open-air thermal pool complexes surrounded by glorious alpine scenery. The resort’s skiing facilities include eight lifts and 25 runs, one of which is almost 13km, the longest in South America. Summer activities also abound, from hiking and horseriding to mountain biking and rock climbing. One ski lift also remains open in the summer for access to the Nevados Bike Park (nevadosbikepark.cl).
