Upper Gulf of California and Colorado River Delta biosphere reserve

The Upper Gulf of California and Colorado River Delta spans 1.6 million hectares, featuring marine habitats, wetlands, and desert landscapes along the Gulf of California.

The Colorado River flowed freely from the Rocky Mountains before 1930, creating vast wetlands covering 7,810 square kilometers with rich biodiversity and indigenous settlements.

The Cucapá people maintained their traditional practices in the delta region, utilizing natural resources through fishing and agriculture methods passed through generations.

Visitors access guided tours and research programs throughout the reserve, with primary entry points through San Luis Río Colorado and Puerto Peñasco in Sonora.

The reserve protects critical habitats for the vaquita porpoise and desert pupfish, two species found exclusively in these waters.
