Cerro Piltriquitrón, Mountain summit in El Bolsón, Argentina.

Cerro Piltriquitrón rises to 2,260 m in the Andes east of El Bolsón, its southern slope crossing into Chubut province. A vehicle track climbs about 13 km to a platform, from which hikers continue on foot past the Bosque Tallado and a mountain refuge before registering for the final ascent to the summit. Lenga and cypress woods cover the slopes.

A fire caused by human negligence burned the lenga forest on the slopes in 1978. In 1997, on the initiative of sculptor Marcelo López, the remaining trunks were carved into the Bosque Tallado.

Locals call the mountain "el Piltri", a shortening of the Mapudungun name Piltriquitrón, which is commonly rendered as "hill hanging from the clouds". The carved figures in the Bosque Tallado, begun in 1997 on the initiative of sculptor Marcelo López, are the mountain's present-day cultural draw.

Access begins at a marked trailhead located east of El Bolsón, with accommodation available on the mountain. Visitors should prepare for changing weather conditions and some steep sections along the way.

Burnt tree trunks have been carved by local artists into an outdoor sculpture gallery depicting forest animals and natural spirits. These artworks are integrated into the forest, creating a surprising experience while hiking.
