Ralco National Reserve, National reserve in Bío Bío province, Chile

Ralco National Reserve covers 12,421 hectares in the Alto Biobío commune, with an average elevation of 1,200 meters. The Callaqui volcano dominates the landscape and has left traces of its activity across the area. Its Andean Patagonian forest includes araucarias, lengas, ñirres and robles.

The reserve was established in 1987 to protect the region's natural resources and maintain ecological balance in the Bío Bío area. This founding action ensured the long-term preservation of the land for future generations.

The Pehuenche communities have lived here for generations and continue to practice traditional activities like pine nut harvesting and grazing their animals. These everyday customs remain woven into the life of the reserve today.

The best time to visit is during warmer months when trails are easy to walk and conditions are favorable. You can hike or fish here, but check with local information centers beforehand to plan your activities.

The reserve's subsoil is protected as a scientific site for mining purposes under Article 17 of Chile's Mining Code, established by Supreme Decree No. 20 of 1 February 2006 and published on 11 May 2006. Any mining work there requires written permission from the President of the Republic, countersigned by the Minister of Mining.
