Cascada de Minas Viejas, Natural waterfall in El Naranjo, San Luis Potosí, Mexico

Cascada de Minas Viejas lies in the municipality of El Naranjo, San Luis Potosí, at 22.22 N, 99.17 W. It consists of two water falls about 50 m high that drop over a rounded, layered rock face into a pale turquoise pool. The water spreads wide and foamy across the upper face, breaks into thinner streams over the uneven stone, and green vegetation grows along the top edge of the rock.

The sources record no mining history for the site itself; the name Minas Viejas is the only link to that past. The waterfall lies in El Naranjo municipality, San Luis Potosí, at 22.22 N, 99.17 W, 16 km from El Naranjo on the road toward La Hincada, at the turnoff for Maitínez and Minas Viejas. It is close to the Tamasopo waterfall group.

The name Minas Viejas, "old mines", recalls the mining past of El Naranjo, the municipality where the falls lie. Today the pool at the base of the two 50-metre drops is used for swimming, and camping is allowed on the surrounding ground. Visitors also continue on to the nearby Laguna de los Patos, where fishing is possible.

The waterfall is reached by taking Highway 80 from San Luis Potosí toward El Naranjo, then continuing on local roads toward La Hincada. Wear sturdy shoes and prepare for a moderate hike through forest terrain with uneven ground.

The two 50-metre falls form a single pool at their base, and camping is allowed on site. From El Naranjo, the access road runs 16 km toward La Hincada before the turnoff to Maitínez and Minas Viejas. Nearby are other waterfalls and the Laguna de los Patos, where fishing is possible.
