The Monte de El Pardo is the largest forested area in the municipality. A holm oak forest covering a surface over  hectares, it is considered the best preserved mediterranean forest in the Community of Madrid and one of the best preserved in Europe. Already mentioned in the Alfonso XI's '''' from the mid 14th-century, its condition as hunting location linked to the Spanish monarchy help to preserve the environmental value. During the reign of Ferdinand VII the regime of hunting prohibition for the Monte de El Pardo became one of full property and the expropriation of all possessions within its bounds was enforced, with dire consequences for the madrilenians at the time. It is designated as Special Protection Area for bird-life and it is also part of the Regional Park of the High Basin of the Manzanares.
