The Patagonian archipelago is a group of islands located in southernmost part of the South American continent.

Spanning over 2,000 miles, the archipelago consists of six major islands – Isla Grande de San Martín, Isla Santa Cruz, Isla RN de San Juan, Isla Tierra del Fuego, Isla Santa María and Isla de los Estados. The archipelago is well-known for its rugged terrain and its expansive wildlife.

Patagonic Archipelago Island


The Patagonian archipelago has a rich history. Its first inhabitants were the Tehuelche, a native people who arrived thousands of years ago and occupied most of the islands. In 1542, Francisco de Mendoza discovered the island group while sailing through what is now called Magellan Strait. He named it Islas del Rey Cristóbal after his king and claimed it for Spain.

In 1776, British captain James Cook sailed through these waters on his famous expedition to chart the Pacific Ocean. Upon reaching San Martín Island, he quickly realized that he was in the new island chain. He named the archipelago both “New Albion” and “Terra Australis Incognita”, meaning, unknown southern land. Captain Cook became a famous explorer due to his voyages through this region and suggested that it be added as an annex of Spain if Mexico separated from her Spanish ally during the American Revolutionary War.

A year later, Juan Pérez de Robla sailed into San Martín Channel with a Spanish expeditionary force in 1789 to counter British occupation of parts of South America including Patagonia by blockading their ports near Chile’s coast; this mission was a failure. The Spanish expeditionary force established settlements in the islands, influencing their cultures and sinking them over time. In 1829, however, Chile declared its independence from Spain and all territories of current day Argentina were united under one new country called “Argentina”.


The climate in the Patagonian archipelago is mainly temperate, with a narrow temperature range and high levels of precipitation. The mean annual temperature is around 18 degrees Celsius, but can vary from 12 degrees Celsius in the north to 28 degrees Celsius in the south.

Most of the islands have a subtropical or tropical climate, as they are located close to Africa and/or South America. In March-April, when winter begins to break down and summer arrives, temperatures often rise dramatically; this is because warm air masses travelling across Chilean Antarctica push cold fronts into these areas. In general , temperature variations are very small from year to year. In the north, however, winter temperatures can be lower than in other Chilean regions due to its distance from the Andes’ warm air masses.

The wind patterns can be surprising and contrary; a calm day may turn into a gale while an island on which there is no sign of sea breeze will instead experience heat waves in summer (during El Niño). At any given moment during the season, winds anywhere within 24 hours could produce warmer or cooler conditions than at another island several hundred kilometres away.


The culture in the Patagonian archipelago is a mixture of Spanish, Chilean, and aboriginal traditions. The Spanish influence can be seen in the predominantly Catholic population and traditional notions such as spanish inheritance laws.

Chile has also had a significant impact on the islands; for example, Universidad de Magallanes is based on Isla Margarita island near Buenos Aires and many university faculties are located here (mainly at La Plata). Aboriginal practices such as shamanism are present but have been largely subsumed by more recent cultural influences. Tourism is a huge industry in the Chilean Antarctica.

The islands are frequented by cruise ships such as Celebrity and Disney Wonder, traveling to various South American cities including Punta Arenas and Buenos Aires (the latter less so than during previous decades).

The island nations of Chile and Argentina have been at loggerheads over international maritime boundaries since their respective independence; neither wishes to cede any territory, despite offers from both sides during negotiations that began in 1953.


The Argentine claim to the islands rests on a lease from Spain that was ratified in 1884. Chile considers the island group part of its continental shelf, and has made repeated claims to them since gaining independence in 1810.

In 1964, a treaty between Argentina and Chile delimited their respective maritime zones; however, this was not recognized by Argentina because it did not include Isla Grande (Atacama). In 1989, an agreement was reached whereby both countries would establish demarcation lines based on accepted international law; this process was completed in 1992.

Government services

The island group forms part of Tierra del Fuego Province, which is divided into the communes of Puerto Williams, Isla Grande and Fitz Roy. There are no airports on the islands; all travel is by sea or air to mainland Chile.

Many islanders engage in subsistence farming and animal husbandry, supplemented by income from tourism. Education is provided mainly through the public school system on Chilean soil, with a limited number of students attending schools on Tierra del Fuego (most notably at Puupuichio School). Health care is also available through clinics and hospitals in Puerto Williams and Puerto San Julian, on mainland Chiloé island.

The islands form part of Tierra del Fuego National Park. There are no other national parks and reserves in the archipelago, but commonwealth status was granted to three of the four main groups: Isla Grande (Chile), El Yunque (Puerto Rico) and Montevideo Bank (), with a unique reserve covering parts of all four ecoregions within Chile’s Austral Islands provincial marine park () that includes many smaller offshore islets such as O’Higgins Rock ().



Tourism is an important part of island life, and services such as transportation, accommodations, food and beverage are widely available. The island’s four main settlements (Puerto Williams, Isla Grande, Fitz Roy and Puerto San Julian) have facilities to accommodate tourists in each case; the fourth settlement of Penas Blancas does not have a permanent population but has a landing strip for air visitors.


The Patagonian Archipelago Island is an archipelago of islands located in southern Chile and Argentina. The archipelago consists of more than 1,500 islands and islets, many of which are Isla del Estrecho National Park. The archipelago is an important tourist destination and contains a great variety of ecosystems, ranging from temperate forests to ice fields.
