El Medano Brook
It is located in the outskirts of Antofagasta (101 km south of it) and 72 km north of Tal Tal. It represents an important centre for many specialists given that just a few kilometres away lies a votive centre for the culture known as los changos, with hundreds of rock paintings.
Over the course of a 5 km stretch you can find rocks and cliffs with paintings and scenes depicting the life of the indigenous changos. It is believed that the paintings date back to between 500 and 1 000 years.
