The Sanctuary is located in the central part of the Baja California peninsula and has unique ecosystems and a great wealth of biodiversity. With an area of 25,000 km2, it is the largest protected natural area in the country.

The Reserve includes the mountain ecosystem (the Sierra Placeres, the Sierra de Santa Clara and the Sierra de San Francisco) the coastal lagoons of Ojo de Liebre and San Ignacio, and the estuaries: La Bocana, El Coyote, El Cardón, El Dátil in the San Ignacio Lagoon.

The diversity of the physical and climatic environments has allowed the development of a very rich wildlife. In the terrestrial portion of the Reserve, 308 species of terrestrial and marine vertebrates (excluding fish) have been found, of which 4 are amphibians, 43 reptiles, 192 birds, and 69 mammals.

With 450 kilometers of coastline, it has a very rich marine and lake ecosystem. Here are the richest banks of abalone and lobster in North America. In addition, the El Vizcaíno Whale Sanctuary is the most important place in the world to protect the gray whale population. This cetacean travels 8,000 kilometers from Chukchi in the Arctic Circle to the Ojo de Liebre and San Ignacio Lagoons, and during the months of December to April, it mates and reproduces.

Sea calves, California sea lions, northern elephant seals, blue whales and four species of endangered sea turtles can also be found in the area.

Every year more than 1,000 calves are born in the lagoons, gradually increasing the population of gray whales.

The lagoons and estuaries annually receive thousands of waterfowl that migrate from the north. This area is considered one of the most important areas for birds that make the Pacific migratory route.
