The southernmost 6000m-peak of the Andes. Marmolejo of course is a volcano.
The ascent is interesting because most of the hike is covered by ice, and not
volcanic debris. Usually the ascent is done from Baños Morales, but access
is also possible from Embalse El Yeso.
View from Valle del Mesoncito
Location: Cajón del Maipo, 20 km from Baños Morales, up the Cajón del Morado
