Los Estratos is a geological formation reached by a hike through La Yesera, located roughly 161 kilometers from Salta and about 27 kilometers from Cafayate along the Río de las Conchas corridor.

The site is known for its striking visual layers formed by stratigraphic plates — bands of sedimentary rock stacked in colorful, horizontal stripes across the landscape. The walk out to Los Estratos from the La Yesera pullout takes approximately 40 minutes.

Signage along the route can be sparse or absent, so navigation requires some attention.

Early morning visits are recommended for the best light and cooler temperatures, and arriving at dawn can mean having the formation entirely to yourself before tour groups from Salta make their way through the quebrada.
