Cuatrociénegas

Poza Azul in Cuatro Cienegas.

Cuatrociénegas (Four marshes) is a desert oasis in northern Mexico. It is a protected natural reserve where unique plant and animal species thrive in the cool pools, called pozas, fed by underground waters percolating up through the desert floor. The area is a UNESCO Biosphere Reserve and has been designated as a Ramsar wetland.

The area is a protected biosphere.

Understand

Cuatro Cienegas is a fragile ecosystem. The number of pools, called pozas, in the valley varies seasonally and a precise count is never completely accurate. The biodiversity of Cuatro Cienegas and its unusual ecosystem has earned it labels like "Desert Aquarium" and "Galapagos of Mexico".

Cool, crystal clear waters make it easy to view the underwater ecosystem.

The town is famous as the birthplace of former Mexican president, Coahuila governor, and leader of the Mexican Revolution, Venustiano Carranza.

Get in

Buses run regularly from the twin border towns of Eagle Pass Texas and Piedras Negras Coahuila. Grupo Senda serves the area through its Coahuilenses buses, and ticket prices from the border are approximately US$20. You can also bus in from the city of Monclova, about an hour away or other points in Coahuila and neighboring states.

Driving to Cuatro Cienegas is more practical, especially if you have a 4WD SUV or pickup. Some pozas and recreational areas are far off the main road. The protected area lies about 4 hours from the U.S. border.

Get around

You can walk around the area near the visitor center at Poza Azul. Some of the more remote pools require 4WD or a good pair of legs (preferably those of a horse). Pools are no longer open for swimming, since new legislation was passed to protect them in 2008.

Fine powdery white gypsum is blown by prevailing winds into sand dunes.
