General Bernardo O'Higgins Base Skyway

Chile's Antarctic frontier where science meets stunning polar wilderness.

General Bernardo O'Higgins Base is a Chilean Antarctic research station located on Cape Legoupil at the northern tip of the Antarctic Peninsula. Established in 1948, it is one of the oldest continuously operated bases on the continent and serves as a hub for Chilean scientific research, meteorological observation, and logistical support in the region.

Visitors — typically arriving via expedition cruise ships or military supply vessels — are treated to dramatic scenery of glaciers, icebergs, and abundant wildlife including penguins, seals, and seabirds. The base is staffed year-round by Chilean Army personnel and scientists, giving it a distinctly functional, frontier character rather than a tourist destination feel.

Access is strictly controlled and visits are usually brief, coordinated shore excursions. Travelers should expect raw, unfiltered Antarctic conditions and carry full cold-weather gear at all times.

• •O'Higgins Base Station — tour the operational Chilean research and military facility.
• •Cape Legoupil shoreline — dramatic coastal scenery with towering glaciers calving into the sea.
• •Penguin colonies — observe Gentoo and Chinstrap penguins in their natural rocky habitat.
• •Weddell and leopard seals — spot these powerful predators hauled out on ice floes nearby.
• •Surrounding icebergs — otherworldly sculpted ice formations drifting through the strait.
• •Antarctic Peninsula panoramas — sweeping mountain and glacier vistas virtually unchanged by time.

Getting around: There is no public transportation infrastructure at O'Higgins Base; movement ashore is entirely on foot during guided excursions. Zodiac inflatable boats ferry visitors between expedition ships and the landing site. All shore movement is escorted and confined to designated areas.

Best time: The austral summer months of November through February offer the mildest temperatures, calm seas, and maximum daylight for wildlife viewing and safe landings.

Local food: Onboard expedition ships serving the base area typically offer hearty international cuisine, but visitors lucky enough to be hosted by Chilean personnel may sample traditional Chilean staples such as cazuela stew or sopaipillas as a warm, welcoming gesture.
