That is the only one Nature Reserve in the Group of Protected Areas of Extremadura nowadays. Actually, it was declared as such in 1994, through a Decree in which the precise description of its limits is reflected.

Regarding its nature values,specially the mountain habitat, Garganta de los Infiernos Nature Reserve forms part of the Site Community Importance (LIC), the so-called "Sierra de Gredos and Valle del Jerte", proposed by the Extremadura Region for it to be included in the Natura Network 2000.

LOCATION: Garganta de los Infiernos is located in the region of Valle del Jerte, in the southeast slope of Sierra de Gredos. It is regarded as the door of entrance to Extremadura from the province of Ávila, a real balcony towards the valley that opens to the plain of Cáceres.

The small extension of the Reserve, 6,800 hectares, is divided into three municipal terms: Tornavacas, Cabezuela del Valle and Jerte.

SOME TIPS FOR TRAVELLERS: Due to the fact that the conditions of the mountain are really hard and the sudden meteorological changes produced that can catch the traveller, it is always recommended to bring warm clothes and protection from the rain.

As regards the difficulty of certain routes, it is convenient to ask for information to the staff of the Reserve, who will advise you about the most appropriate routes for each group according to your preferences.

Many of the species of flora of the Reserve are strictly protected due to the fact that they are very scarce, thus it is banned to recollect any plant.

Los Pilones, the zone which attracts the largest groups of visitants, is the most vulnerable place due to that. Therefore, it is recommended to be specially careful in order to avoid the rubbish being thrown and help it to keep on being a beautiful place where the intensive use by the public and its conservation are compatible.
