Los Alerces National Park, located in the Patagonian Andes of Argentina's Chubut Province, is renowned for its spectacular glacially sculpted landscapes, including moraines, cirques, and crystal-clear lakes. Established in 1937 to protect the endangered alerce tree species, the park preserves one of the largest and best-conserved alerce forests in the world. These ancient trees, some over 2,600 years old, are among the longest-living tree species globally. The park's diverse ecosystems range from dense temperate forests to alpine meadows beneath rocky peaks, with a distinct tree line around 1,400 meters. The park encompasses a chain of lakes connected by rivers, such as Lake Menéndez, home to the largest known alerce tree in Argentina. Its western boundary borders Chile, and it covers approximately 187,000 hectares of national park and additional protected reserve areas. Declared a UNESCO World Heritage site in 2017, Los Alerces is a vital refuge for endemic and threatened flora and fauna, showcasing one of the last pristine Patagonian forests and offering visitors breathtaking natural beauty and ecological significance.

Tip: The best time to visit Los Alerces National Park is during the southern hemisphere's summer months (December to March) when weather conditions are milder and most trails are accessible. Visitors are encouraged to book guided boat tours in advance to explore the alerce forest near Puerto Sagrario on Lake Menéndez, which is a highlight of the park. Discounts may be available for students, seniors, or groups at official entrances. Due to the park's remote location and protected status, it is advisable to prepare for limited services and carry necessary supplies. Early reservations for accommodations in nearby Villa Futalaufquen are recommended during peak season.
