In El Potosí National Park there are species in different risk categories. With a total surface area of 2,000 hectares, this area includes pine and oak forests that protect an important number of springs, among them cycad, iris, and biznaga. El Potosí National Park was established in 1936 by President Lázaro Cárdenas.
It is an important refuge for some species of migratory birds whose routes pass nearby. El Potosí National Park is located in the highest parts of the mountainous massifs of the Serranía de Rioverde, in the municipality of Rioverde, in the state of San Luis Potosí, which was established by Federal Executive Decree, published in the Diario Oficial de la Federación on September 15, 1936, with an area of approximately two thousand hectares.
El Potosí National Park presents a scenic beauty and a diversity of flora and fauna that constitute an attraction to carry out tourism activities of low environmental impact, such as hiking, photography, observation of flora and fauna.
