About Bernardo O'Higgins
Bernardo O'Higgins National Park is the largest national park in Chile, featuring massive ice fields, fjords, and glaciers. The park contains part of the Southern Patagonian Ice Field and numerous glaciers. It is home to diverse wildlife including Andean condors and marine mammals.
Fauna
The park hosts a diverse array of wildlife adapted to its challenging environment. Marine mammals include humpback whales, southern sea lions, and leopard seals. The terrestrial fauna features endangered species such as the huemul (South Andean deer), puma, and Andean condor. The park is also home to numerous bird species, including the Magellanic woodpecker, black-browed albatross, and various species of petrels and cormorants that nest along its rugged coastline.
Flora
The park's vegetation varies significantly with altitude and exposure, featuring three distinct ecosystems: Magellanic subpolar forests, Andean-Patagonian forests, and high-altitude tundra. The lower elevations are dominated by evergreen species such as coigüe (Nothofagus betuloides) and canelo (Drimys winteri), while higher areas support hardy alpine species adapted to extreme conditions. The park also contains extensive areas of moorland vegetation and unique plant communities adapted to the harsh subantarctic environment.
Geology
The park's dramatic landscape was shaped by extensive glacial activity, featuring the Southern Patagonian Ice Field, the largest extant ice field in the Southern Hemisphere outside Antarctica. The terrain encompasses numerous fjords, channels, and glaciers, including the renowned Pío XI Glacier, the largest in South America. The region's geology is characterized by metamorphic rock formations, steep valleys carved by glacial movement, and dramatic mountain ranges including peaks reaching over 3,000 meters in height.
History
The park was established in 1969 and named after Bernardo O'Higgins, Chile's independence leader and first head of state. The region has a rich history of indigenous peoples, including the Kawésqar and Aonikenk, who navigated these waters and lands for thousands of years. The area played a significant role in early European exploration, with notable expeditions including those of Juan Ladrillero in 1557 and Pedro Sarmiento de Gamboa in 1579. The park's creation marked Chile's commitment to preserving one of the world's largest remaining wilderness areas.
Notable Features
Bernardo O'Higgins National Park is distinguished by several remarkable features, including the massive Pío XI Glacier, which, unlike many retreating glaciers worldwide, has been advancing. The park contains part of the Southern Patagonian Ice Field, numerous fjords, and pristine channels ideal for navigation. The Mount Balmaceda area offers spectacular views of glaciers and mountains, while the Last Hope Sound (Última Esperanza) provides access to remote wilderness areas. The park's vast size and limited accessibility have helped preserve its pristine natural state, making it one of South America's last true wilderness frontiers.
Climate & Weather
Bernardo O'Higgins National Park experiences a subpolar oceanic climate characterized by cool temperatures year-round and significant precipitation. Average temperatures range from 6°C (43°F) in winter to 14°C (57°F) in summer, with frequent rainfall throughout the year averaging 4,000mm annually. The park's weather is heavily influenced by its proximity to the Southern Patagonian Ice Field, creating highly variable conditions that can change rapidly. Visitors should be prepared for strong winds, sudden storms, and occasional snowfall even during summer months.
