About Parque Marítimo Bernardo O’Higgins

Parque Marítimo Bernardo O’Higgins is Chile's largest national park, offering vast wilderness landscapes of fjords, glaciers, and rugged mountains, ideal for adventurous trekking, glacier exploration, and wildlife observation in one of the most remote parts of Patagonia.

Wilderness Landscape & Natural Heritage

Parque Marítimo Bernardo O’Higgins, established in 1969, is the largest national park in Chile and one of the most expansive protected areas in South America, encompassing approximately 3.5 million acres of pristine wilderness in the southern region of Patagonia. The park stretches along the southern stretches of the Patagonian fjords, featuring a dramatic landscape shaped by glaciers, deep fjords, and towering peaks of the Andes mountain range. It includes notable glaciers such as the Pío XI, the largest glacier in the southern hemisphere outside Antarctica, which advances unlike most glaciers in the world. The park's ecology is characterized by dense lenga and coihue forests at lower elevations, transitioning to subpolar and tundra environments at higher altitudes. Wildlife includes Andean condors, guanacos, pumas, and a diverse array of marine life in the surrounding fjords. Access to the park is limited and predominantly by boat or small aircraft, making it a destination for experienced trekkers and adventure travelers seeking remote, off-the-beaten-path experiences. Key recreational activities include multi-day trekking routes, glacier and iceberg viewing, kayaking in sheltered fjords, and wildlife photography. Landmarks in the park include the renowned Pío XI Glacier, the Jorge Montt Glacier, and the southern reaches of the Patagonian Ice Field. Visitor appeal lies in its raw natural beauty, solitude, and the challenge of exploring a vast wilderness with minimal infrastructure. The park's remoteness and challenging weather patterns require careful planning and preparation for those wishing to explore its rugged terrain.
