Area History

The region around the General Carrera Lake / Buenos Aires has been home to various indigenous communities throughout history. In recent years, it has gained popularity as a tourist destination due to its natural beauty and unique attractions.

The shores of General Carrera Lake / Buenos Aires began to be inhabited by Argentine, Chilean, and European settlers in the early 20th century. However, in 1971 and 1991, the eruption of the Hudson Volcano wreaked havoc in the area, which relied primarily on sheep farming.

This area also holds significant cultural and archaeological importance, as it was inhabited by the Tehuelche people in the past. According to a recent study conducted in 2017 by the National Indigenous Development Corporation (CONADI) in Chile Chico and its surroundings, oral accounts of the first settlers arriving in the area were found, including families of Mapuche origin in the year 1896.
