Volcán Lonquimay (2,865 m) rises inside the Malalcahuello area of La Araucanía, where CONAF's Reserva Nacional Malalcahuello has protected araucaria forest since 1931. The climb leaves from Malalcahuello in the morning, and the approach is framed by araucarias, with coigüe, lenga and ñirre in the forests around the volcano. Its slopes are wide and open, which makes it a good mountain for pairing a summit day with a ski descent.
After a briefing, your certified mountain guide fits everyone with crampons, ice axe, helmet and harness, all included. The ascent to the crater takes about 4–5 hours, and time on top depends on conditions. Lonquimay's crater is large and glaciated, and in December 1988 a side vent at its base, Volcán Navidad, began an eruption that lasted more than a year. You come down on foot or, if you are an advanced skier, on skis.
Back in Malalcahuello the same day, you can finish at the hot springs nearby. The whole day asks for 5–7 hours of continuous effort. You do not need technical experience to descend on foot, and groups stay small, up to 6 people, with transfers from Malalcahuello and a trail lunch pack included.
