Tiny Chochís, 360km east of Santa Cruz, sits at the base of the imposing red rock known as la Torre. The main reason for visiting is to see the remarkable Santuario Mariano de la Torre, a religious sanctuary and memorial built to commemorate the victims of a flood. Though relatively modern (the disaster occurred in 1979), the wood carvings that adorn the sanctuary are the rival of anything seen in the Jesuit missions and the site has a palpable sense of mourning that allows you to share in the grief of the townsfolk.
The surrounding countryside is great for walking, and local guides can take you to waterfalls, stunning viewpoints and hidden natural pools. In 2018, 12 street artists from around the world visited Chochís and spent a week painting as part of a festival. Their evocative murals can be seen on buildings around the main square.
