La Hiruela is a mountain town that suffered a dramatic population abandonment in the first decades of the 20th century. The isolation and remoteness of the main communication routes, together with the scarcity of resources in a thankless mountain range, caused a constant emigration of the population towards the big cities to leave a territory where rural life was difficult. The region of the black towns of Madrid and Guadalajara was known as the “sierra pobre”, in comparison with the “sierra rica” of upper Lozoya and the upper basin of the Manzanares and Guadarrama rivers. The rise of active tourism and recreational activities in the environment have caused a resurgence of a new lifestyle dedicated to active leisure and rural tourism products. Crafts, gastronomy, ethnography, hiking, mountain biking, landscape interpretation or nature photography, among many other things, make up an interesting range of attractions that inevitably seduce travelers who visit La Hiruela and the rest of the towns and natural landscapes of Sierra del Rincón, declared a Biosphere Reserve in 2005 by UNESCO.
