Cape Horn National Park is located at the southernmost tip of South America and covers approximately 631 km² (244 sq mi). The park includes the Wollaston and Hermite archipelagos, a remote subantarctic region shaped by strong winds, rugged coastlines, and cold maritime weather.
Created in 1945, the park belongs administratively to Chile’s Antarctic Province in the Magallanes and Chilean Antarctica Region. Its landscape consists mainly of low mountains, rocky islands, forests, peat bogs, and channels. The highest point is Mount Hyde on Wollaston Island, reaching 670 m a.s.l. Summers are cool, with temperatures rarely exceeding 12–13°C (54–55°F), while winters are frequently cold and windy, often with temperatures below freezing.
The park’s greatest attraction is its isolation and its connection to the legendary Cape Horn, one of the world’s most famous maritime landmarks. For centuries, this remote headland represented one of the greatest challenges for sailors navigating between the Atlantic and Pacific Oceans. Although Cape Horn is traditionally regarded as the southern tip of the Americas, the actual southernmost point is Águila Islet in the Diego Ramírez Archipelago, located about 105 km (57 NM) farther south.
Getting There
Reaching Cape Horn National Park is an adventure in itself. Most visitors arrive by air or sea through Puerto Williams, the southernmost city in the world and the main gateway to the park. Expedition cruises and local tour operators also offer trips from Ushuaia in Argentina and from Punta Arenas, the capital of Chile’s Magallanes Region.
Cape Horn lies near the northern boundary of the Drake Passage, where the Atlantic and Pacific Oceans converge. The cape was discovered and named in 1616 by Dutch navigators Willem Schouten and Jacob Le Maire after the Dutch city of Hoorn.
For centuries, Cape Horn was one of the world’s most important maritime routes and also one of its most feared. Violent storms, massive waves, strong currents, and drifting icebergs made navigation extremely dangerous for sailing vessels traveling between the oceans.
Today, the Chilean Navy maintains a permanent station on Hornos Island that includes a lighthouse, a chapel, residential facilities, and a monument dedicated to sailors who lost their lives attempting the crossing. The surrounding area forms part of Cape Horn National Park, which became a UNESCO Biosphere Reserve in 2005.
Despite its harsh conditions, Cape Horn has become an increasingly popular destination for expedition tourism. Modern cruise vessels now allow travelers to experience one of the planet’s most remote and legendary maritime landscapes.
Exploring the Park
Weather permitting, visitors arriving at Hornos Island can disembark and follow the marked trail leading to some of the park’s most iconic landmarks. These include the Albatross Monument, the Monumental Lighthouse, the Monument to the Unknown Sailor, and the small chapel maintained by the Chilean Navy. The area also offers opportunities to observe seabirds and marine wildlife in one of the world’s southernmost inhabited regions.
Inaugurated on December 5, 1992, the Albatross Monument was designed by Chilean sculptor José Balcells. Built from steel plates shaped like an albatross in flight, the monument pays tribute to the thousands of sailors who lost their lives attempting to round Cape Horn, one of the most feared maritime passages in history.
South of the archipelago lies the Drake Passage, the turbulent body of water separating South America from Antarctica and considered the gateway to the Antarctic continent.
Fauna: Cape Horn National Park protects a rich marine and subantarctic ecosystem inhabited by whales, dolphins, sea lions, elephant seals, marine otters, and occasionally leopard seals. Birdlife is especially abundant and includes albatrosses, giant petrels, Magellanic penguins, and Dominican gulls. The surrounding waters are also home to species such as the southern right whale, the Chilean dolphin, and the austral dolphin.
Flora: Despite its harsh climate, the park supports a unique subantarctic vegetation composed mainly of mosses, lichens, peatlands, grasses, and small wind-shaped forests. Native tree species include coigüe, ñirre, and canelo, all adapted to persistent winds, cold temperatures, and high humidity.
The Cape Horn archipelago is internationally recognized for its exceptional bryophyte diversity. Scientists have identified more than 750 species of mosses and liverworts in the region, making it one of the world’s most important hotspots for non-vascular plant life.

Cape Horn National Park is located in Chile’s southernmost archipelago and can only be reached by sea or air. Most visitors travel from Puerto Williams, Punta Arenas, or Ushuaia in Argentina aboard expedition cruises or guided tours.
No. The park is located on remote islands south of Tierra del Fuego, so there are no roads connecting it to mainland Chile or Argentina.
The best time to visit is during the austral spring and summer, from November to March, when weather conditions are generally milder and daylight hours are longer.
Popular activities include trekking, wildlife observation, photography, birdwatching, and expedition cruises through the channels and fjords surrounding Cape Horn.
Yes. Due to the region’s remote location and unpredictable weather, most visitors explore the area through guided cruises or organized expeditions.
Camping is generally not permitted because of the fragile ecosystem and severe weather conditions. Most travelers stay aboard expedition vessels or in Puerto Williams.
Visitors may observe albatrosses, penguins, giant petrels, sea lions, dolphins, whales, and other marine species typical of the subantarctic region.
Most expedition cruises and guided tours last between 3 and 7 days, depending on departure point, weather conditions, and itinerary.
Yes. Visitors can see the Cape Horn lighthouse, the Albatross Monument, the small chapel, and other landmarks connected to the region’s maritime history.
