Cabo de Hornos National Park: A Complete Guide

Cabo de Hornos National Park is the world's southernmost national park, protecting 63,093 hectares of subantarctic archipelago where the Pacific and Atlantic oceans meet. Landings on Hornos Island succeed only 50–60% of the time even in summer, so plan for flexibility. The park lies 12 hours by boat from Puerto Williams, and most visitors arrive on expedition cruises between October and April.

Where Is Cabo de Hornos National Park and How Do You Get There?

Location and Geography

The park covers the Wollaston and Hermite island groups at the southern tip of South America, in Chile's Magallanes region. It sits about 12 hours by navigation from Puerto Williams, the world's southernmost city, which serves as the administrative hub. The archipelago is one of the least human-modified areas in southern South America, with microclimates that support surprising plant diversity. The terrain is low-lying, with small peaks and deeply indented bays and channels.

Reaching the Park from Punta Arenas or Puerto Williams

Most travelers fly into Punta Arenas (Presidente Carlos Ibáñez del Campo Airport, code PUQ), then either take a 30-minute flight to Puerto Williams (Guardiamarina Zañartu Airport, code WPU) or board an expedition cruise that sails from Punta Arenas to Ushuaia with a stop at Cape Horn. From Puerto Williams, local skippers and charter sailboats offer trips through the Beagle Channel and Nassau Bay. There is no road access. Landing on Hornos Island requires a permit and is only possible via expedition vessels or private yachts.

The Only Practical Way to Visit: Expedition Cruises

Expedition cruises typically last 4–7 days and include a landing at Hornos Island, weather permitting. Small ships carrying 100–200 passengers are the norm. Book several months ahead for the November–March high season. Independent sailors can arrange trips from Puerto Williams, but must register with CONAF and pay the entrance fee.

What to See and Do in Cabo de Hornos National Park

Hornos Island: Lighthouse, Monument, and the End of the Continent

A 500-meter wooden walkway and staircase lead from the landing beach to the inhabited lighthouse and the Albatross Monument, a sculpture honoring sailors lost rounding the cape. The lighthouse is staffed by the Chilean Navy and marks the southernmost point of South America. The walk takes about 30 minutes round trip, but strong winds can make it strenuous. The views over the Drake Passage are stark and unforgettable.

Subantarctic Forests and Wildlife

The park protects the world's southernmost forests, where trees grow short and squat due to relentless winds. Magellanic tundra, peat bogs, and cushion plants cover the islands. Wildlife includes southern giant petrels, albatrosses, storm petrels, skuas, sea lions, and Magellanic penguins. Whale sightings (humpbacks and orcas) are possible during the approach. The park is part of the Cape Horn Biosphere Reserve, designated by UNESCO in 2005.

The Cape Horn Biosphere Reserve

The reserve covers 4.88 million hectares, including 1.9 million hectares of land and 2.97 million hectares of marine area. It encompasses tundra, high Andean habitats, glaciers, and permanent watercourses. This designation recognizes the area's global ecological significance and supports research and conservation.

When to Go and What to Expect

Best Season: October to April

The official season runs from October to April, with November through March being peak time. Summer temperatures range from 3°C to 10°C (37–50°F), but fierce winds, rain, and even snow can occur any day. Winds can reach 160–220 km/h, and the Drake Passage is notorious for rough seas. October and late March are shoulder seasons with fewer crowds and sometimes lower prices.

Weather and Sea Conditions

Be prepared for rapid changes. Landings are often canceled due to high winds and swells. Even in summer, the success rate for landing at Cape Horn averages only 50–60%. Experienced travelers book multiple sailing days in Puerto Williams rather than a single attempt. Seasickness medication is advisable for the Drake Passage crossing.

Fees and Registration

All visitors must register with CONAF and pay the entrance fee. As of 2024, the fee for foreign adults is about 10,000 Chilean pesos (around $11 USD), but fees are subject to change — check the official site for current rates. Bookings can be made online at pasesparques.cl. The park is open year-round, but visitor services are limited outside the October–April season.
