Yerba Loca is a campground set within the Yerba Loca Nature Sanctuary, a 390-square-kilometer protected area in the Andes east of Santiago, in the commune of Lo Barnechea.

The sanctuary takes its name from the Estero Yerba Loca, a stream fed by glacial meltwater originating above 3,900 meters at Glaciar La Paloma.

The park encompasses mountains, forests, and river corridors, with the terrain rising all the way to Cerro El Plomo at more than 5,200 meters. The campground is one of three camping zones within the park.

Facilities on site include picnic areas, restrooms, showers, and drinking water. A visitor center at Villa Paulina runs on solar power.

Hiking trails range from accessible valley walks along the vivid blue estero to expert-level routes toward the high glaciers. The park is open daily and tickets are sold online only.
