Our Location 

El Sauce Observatory is located in the Río Hurtado Valley in Chile. This location shares the same great sky with important scientific observatories such as Cerro Tololo Interamerican Observatory (CTIO) and Gemini South. Thanks to its remote location far from major cities it benefits from one of the darkest skies in the world.
