El Tepeyac National Park is one of a number of federally recognized national parks in Mexico that are protected natural areas and administered by the federal National Commission of Protected Natural Areas (CONANP), a subsidiary of SEMARNAT (Ministry of Environment). It is one of the few green areas located north of the Mexico City suburbs. 95% of its territory is located in Gustavo A. Madero, D.F. Borough and 5% in the municipality of Tlalnepantla de Baz. This is one of the large expanses of artificial forest of eucalyptus and was reforested in the first half of the 20th century in the Federal District. The designated territory for the National Park is the Tepeyac Hill, place known for the legend of the apparition of the Virgin of Guadalupe to the indigenous Juan Diego. From the top of the hill a whole view of the Valley of Mexico can be seen. However, this place is threatened by the urban sprawl growing in the surroundings. This park covers part of the Sierra de Guadalupe mountain range and was created through a decree issued on February 18, 1937. Originally it had an extension of 1,500 ha. Even though several other authors indicate different current numbers depending on the type of topographic study applied. 56% of the park is legally an "ejido" and the 44% left is privately owned. Because once the territory had a completely lack of vegetation and was restored after reforestation activities, by decrees issued in 1926, 1937 and 1972, El Tepeyac is now considered a protected National Park under reforestation programs of Local and Federal administration.
