El Chaltén is a small mountain village in Santa Cruz Province, Argentina. It is located in the riverside of Rio de las Vueltas, within the Los Glaciares National Park (section Reserva Nacional Zona Viedma) at the base of Cerro Torre and Cerro Fitz Roy mountains, both popular for climbing. For this reason this village was named Argentina's Trekking Capital or Capital Nacional del Trekking. It was built in 1985 to help secure the disputed border with Chile. Today the sole reason for its existence is tourism.
