Parque Nacional Bernardo O’Higgins is the largest protected area in Chile and one of the largest national parks in South America, encompassing extensive fjords, icefields, and temperate rainforests. The park spans remote portions of the Aysén Region and Magallanes Region, adjoining other protected areas and international waters, and contains iconic features such as the Southern Patagonian Ice Field, the San Rafael Glacier vicinity, and the Cabo de Hornos maritime approaches. Its scale and location make it central to transboundary conservation initiatives involving Argentina and multinational scientific programs.
The park occupies a swath of the Patagonian Andes and coastal archipelagos bordered by the Pacific Ocean, Gulf of Penas, and interior icefields near the Santa Cruz Province frontier, with coordinates overlapping map sectors used by Instituto Geográfico Militar and Servicio Hidrográfico y Oceanográfico de la Armada de Chile. It interfaces with adjacent protected areas such as Parque Nacional Laguna San Rafael, Reserva Nacional Cerro Castillo, and buffer lands administered by CONAF and regional authorities in Aysén del General Carlos Ibáñez del Campo Region. Boundaries follow fjords, mountain ridgelines, and maritime limits set under historical accords involving Chile and foreign cartographic surveys by the Hydrographic and Oceanographic Service of the Chilean Navy. The park’s vast area includes archipelagos mapped in charts by James Cook and later explored during expeditions like those of Phillip Parker King and Ferdinand Magellan.
Indigenous presence predates European contact, with ancestral use by Kawésqar and Yaghan peoples documented in ethnographic records and museum collections such as those of the Museo Nacional de Historia Natural. European exploration during the Age of Discovery brought cartographers, sealers, and voyages by figures connected to HMS Beagle narratives and British Admiralty surveying. Nineteenth- and twentieth-century interest from Chilean state actors, private enterprises, and scientific institutions led to proposals for protection culminating in legal instruments under presidents aligned with conservation trends similar to those that produced Parque Nacional Torres del Paine and other national designations. The park was formally created in 1969 through legislation and administrative actions involving CONAF and national ministries, later expanded by executive decrees influenced by studies from Universidad de Chile researchers and international bodies such as the IUCN.
The park hosts ecosystems characteristic of Valdivian temperate rainforest, subantarctic Nothofagus forests, and montane tundra associated with the Southern Patagonian Ice Field and adjacent fjord waters studied by SERNATUR and academic programs at Universidad de Magallanes. Faunal assemblages include marine megafauna recorded by surveys linked to CITIZEN SCIENCE projects: populations of Southern elephant seal and Humpback whale frequent nearby channels, while terrestrial species such as Guanaco, Andean condor, Puma, and endemic passerines documented in collections at Museo Nacional de Historia Natural inhabit different biomes. Botanical diversity features genera like Nothofagus, Drimys, and bryophyte communities important to research by institutes including Instituto de la Patagonia and programs funded by the Consejo Nacional de Ciencia y Tecnología. Migratory bird routes connect the park to flyways studied by BirdLife International partners and national ornithological societies.
Major ice masses within the park are part of the Southern Patagonian Ice Field, including outlet glaciers that feed fjords and proglacial lakes monitored by glaciologists from Universidad de Chile, Universidad de Magallanes, and international teams associated with SCAR and GLIMS. Notable glacial landmarks and maritime glaciers have been focal points for studies on climate change published in journals partnering with CONAF and research bodies like Comisión Nacional de Investigación Científica y Tecnológica. The park’s landscapes include steep fjords, hanging valleys, cirques, and moraines mapped in atlases produced by the Instituto Geográfico Militar and documented during expeditions sponsored by organizations such as WWF and The Nature Conservancy.
Human presence is sparse, with historical use by Kawésqar and seasonal activity by fishers and shepherds referenced in regional archives and oral histories curated in collections at Museo Regional de Aysén. Access is primarily by sea and limited air transport, with routes originating in Punta Arenas, Coyhaique, and smaller coastal ports; navigation follows charts by the Hydrographic and Oceanographic Service of the Chilean Navy. Scientific stations and temporary field camps are supported by universities and research organizations including Universidad Austral de Chile and international collaborators. Maritime transit is regulated under national statutes implemented by the Maritime Authority of Chile and operationalized through coordination with local municipalities such as Comuna de Aysén.
Management is led by Corporación Nacional Forestal in coordination with regional governments and stakeholders including indigenous organizations representing Kawésqar claims, conservation NGOs like WWF and Conservation International, and academic partners. Conservation measures address pressures from climate change, fisheries, and nascent tourism, informed by monitoring programs financed by agencies such as Conicyt and international grants from bodies like the Global Environment Facility. Transboundary cooperation with Argentina and participation in networks such as the Patagonia Conservation Initiative aim to integrate landscape-scale conservation across the Andes and austral archipelagos. Legal frameworks reference national protected area laws and international instruments endorsed by Chile in forums including the Convention on Biological Diversity.
Visitor activities are limited and concentrated around maritime cruises, kayak expeditions, and guided trekking promoted through regional tourism boards like SERNATUR and private operators based in Punta Arenas and Coyhaique. Wildlife watching, glacier viewing, and expedition-style travel are marketed in collaboration with travel associations and adventure companies compliant with standards set by CONAF and regional tourism offices. Scientific tourism and educational programs partner with universities and museums such as Museo de la Exploración to offer interpretive experiences that emphasize low-impact practices aligned with guidelines from IUCN and conservation NGOs.
