Nalcas National Reserve

Nalcas National Reserve is a mountain protected area in the Andes covered by native Araucaria forests on volcanic soils, with trees reaching up to 130 feet (40 meters) tall. Steep slopes, ravines, and streams cut through the terrain, creating varied habitats across the landscape.

The reserve was established in 1967 after intensive logging during the 1950s had damaged much of the original forest. Protection allowed the remaining old-growth Araucaria trees to survive and the forest to recover over time.

The Araucaria forests hold deep meaning for local Mapuche communities, who have gathered and hunted here for centuries and consider the trees culturally important. These ancient trees shape how people experience and relate to the landscape today.

Access to trails begins at Malalcahuello village, where CONAF rangers provide information and guidance before visitors head out. The steep mountain terrain requires sturdy footwear and caution, as paths can be muddy or slippery, especially after rain.

The reserve shares a boundary with Malalcahuello Reserve at the volcano Lonquimay summit, together forming one large combined protected zone. This arrangement allows wildlife to move freely between both areas, supporting healthier animal populations.
