Guadalajara is the northernmost province of Castilla-La Mancha, embraced by the Iberian and Central Mountain Ranges that create a jagged terrain that only becomes smoother in the southeast, toward the province of Madrid to which it is naturally joined by the River Henares Corredor.

A good example of the natural beauty that Guadalajara holds can be seen visiting the black architecture towns that show us how the materials from the natural surroundings were used. The landscapes in this province are among the most beautiful to be found in Castilla-La Mancha.


One of the most lovely protected sites, the Hayedo de Tejera Negra, also one of the southernmost Common Beech formations in Europe, was established there to take advantage of the unique microclimatic conditions.


The biggest protected nature spot in Castilla-La Mancha is also to be found in this province: the Alto Tajo Nature Reserve which, in its 105,721 hectares, encompasses the land of 35 towns in Guadalajara and 2 in Cuenca.


This vast space offers extensive plateaus affected by the river network, particularly the Rivers Tajo and Gallo, that have created, with the passage of time, deep gorges and ravines in recent geological epochs. At the same time, the pines, oaks, Portuguese oaks and junipers are the more important species, lending green and ochre tones and creating a characteristic tone in the landscape according to the time of year.


The Hoz de Pelegrina (Pelegrina Ravine) in the Barranco del Río Dulce Nature Reserve, in the Altas Tierras de Sigüenza (Sigüenza Heights) is also a great place to visit given its rich and varied biodiversity and state of conservation.


Among all the richness of the heritage of this province’s towns, one must highlight the Historical-Artistic Sites of: Atienza, Brihuega, Hita, Molina de Aragón, Palazuelos, Pastrana and Sigüenza.
