The Enladrillado plateau consists of large, rectangular volcanic basalt blocks that appear artificially arranged, though they are of natural geological origin.
The reserve protects the habitat of the endangered Ruiz-Leal's frog.
The Lircay River serves as a critical biological corridor for the dispersal of native forest flora, including Nothofagus obliqua and Nothofagus alpina.
Altos de Lircay is part of the Vilches area, which sits atop a significant volcanic fault line.
The reserve has functioned as a testing ground for forest fire prevention techniques within the Chilean Andes due to the high density of flammable native brush.
It sits at elevations spanning from 600 meters to over 2,500 meters above sea level.
Reserva Nacional Altos de Lircay is a mountainous protected area in the Andes of the Maule Region, characterized by its ancient Nothofagus forests and volcanic geological formations. The reserve serves as a primary access point to the Enladrillado, a large, flat basaltic plateau often associated with local astronomical and geological study. It encompasses diverse ecosystems ranging from deciduous forests at lower elevations to high-altitude Andean environments. The Lircay River watershed defines much of the area's geography, providing water for the various hiking corridors. Visitors frequently encounter endemic species such as the Andean condor and the mountain vizcacha. Hiking remains the central activity, with trails leading to summits, glacial lagoons, and panoramic overlooks of the surrounding peaks. The reserve is managed by CONAF as part of the National System of Protected Areas.

Bring trekking poles to navigate the steep, loose volcanic gravel found on higher elevation trails.
Always register your intended hiking route with the park rangers at the entrance station for safety.
Ensure your footwear is waterproof, as trails frequently intersect with high-mountain runoff streams.
Attempting the ascent to the Enladrillado without proper cold-weather gear, even in summer, as temperatures drop rapidly at altitude.
May be subject to intermittent closures during winter months or extreme weather events; check official CONAF status before departure.
Strict 'Leave No Trace' principles apply; packing out all waste and refraining from feeding wildlife is mandatory.
