The walls of the upper Duero

Welcome to this route through the time tunnel.

The route, of about 300 km, passes in its first half around the Duero River, mainly on its southern slope, and returns through the Sierra de Pela, which traces the southern border of the province of Soria, with its neighbors ones Segovia and Guadalajara .

This area next to the riverDuero, was very active during the Middle Ages and the reconquest. The continuous fights between the Muslim and Christian kingdoms first, and later on between Aragon and Castile, has left us a rich legacy in the form of fortified towns, such as Almazán, Maderuelo, Ayllón or Rello; castles such as Berlanga de Duero or Gormaz, and muslim watchtowers such as El Tiñón, spread over this territory.

And if we want to go back even further into the past, in the area of Tiermes, we can find a great testimony of the first settlers in this territory.

The artistic touch of the route is provided by the numerous and beautiful examples of arcaded Romanesque such as the Church of San Miguel in San Esteban de Gormaz, the first of this style in Castile; or the Burgo de Osma Cathedral, a whole mix of architectural styles.

Dovecotes, fences, farmyards, wine cellars, winepresses, agricultural crops …, they will give us a view on the people´s day to day in this area.

And the natural environment … Banks of the Duero River and tributaries, Riaza´s River Gorges, Ayllón montains, Tiermes holm-oak woods, Barahona Highlands and the River Talegones Canyon, are areas of great ecological interest protected by the Natura 2000 Network within this route.

A multitude of places patiently await surprise us. Do you want to discover them?.


This is the first of the planned routes that includes a shortcut, in this case, with different alternatives depending on whether you prefer more or less road, or where you want to continue. This shortcut Tiermes-Caracena-Gormaz-El Burgo de Osma, is also the first connection between the projects of Caminos de Frontera – cycling zone and Montañas Vacías, in its XL version. And there will be more as long as the next developments allow, and also with other very interesting projects like the ones you can find here in the Connecting projects section.

CF+ Caracena-Carrasca de Valderromán (ESP)

CF+ San Baudelio-Caltojar-La Veruela.

This last CF+, does not have a separate website or guide as it´s part of the route Watchtowers and fortresses in the valleys of the Escalote and Torete rivers.



To all those who either with your encouragement or with your advice and technical support, you are also contributing to make all this gradually moving forward. Thanks to my family who are there at all times and thanks also to the great people that I´m meeting throughout this trip. You all know that you are in my mind and in my heart.
