It is a linear route of 8 km (one way) that runs between the church of Ucedo and the picnic area of ​​Valbuena, the round trip being the same way. Most of it runs parallel to the Retuerta stream.

During the tour you will see 6 flour mills (some better preserved than others),
petroglyphs, numerous fountains, the Peña el Oso or Peña la Muria that marks the boundary between the two towns.

Being in a riverside environment, the vegetation of this type of areas predominates, such as birch, alder, poplar ... but there is also heather, pine, broom, oak, hawthorn...etc. There is a varied fauna such as wild boar, roe deer, wolf, fox, hare, eagle, cuckoo, great spotted woodpecker, lizard...etc.

UCEDO MILLS

In the Canalina area there are 3 mills, the Raimundo, the Canalín and the Nuevo,
dedicated to the milling of cereal. They are monohydraulic, consist of a single horizontal or rolling wheel to move the drive shaft. It also consists of two grinding wheels to grind the cereal grain and turn it into flour.
They were used by the residents of the town to transform the grain into flour to feed animals or for human consumption.

VALBUENA MILLS

In Valbuena there were 5 industrial mills, which grind cereal for most of La Cepeda.
At present, you can see the remains of 3 of them, the Ramón mill, the Victoriano mill and the Pedro mill, which is the only one that sifted the cereal (it separated the shell of the cereal from the flour) for human consumption.
They are mini-hydraulic mills, they consist of a single horizontal or rolling wheel to move the drive shaft. It also consists of two grinding wheels to grind the cereal grain and turn it into flour.

Route that crosses 14 km in a circular way at the birth of three of the sources that in Los Barrios de Nistoso give rise to the Tuerto river.

The Remolinos streams in Nistoso and the Refleyu del Rebiján and the Riu streams in Tabladas, at 1,280 meters of altitude in a region where the language and culture of León offer the visitor a powerful asset.

Through a pleasant walk you can enjoy this bordering mountainous area between the regions of La Cepeda and El Bierzo, between the Miño and Duero basins.

The route begins on the track that leads to the sports center, from where you take an old road that, between the holm oaks and oaks installed on sunny slopes, accesses the Valdecouso area, an important chestnut grove that offers, when autumn comes, its appetizing fruits; chestnuts.

Little by little, the path narrows and saves the unevenness between the previous spot and the Arroyo del Mostruelo, also known as Arroyo de la Górgora, in reference to the sound that the water makes when it springs up.

Oak, holm oak and chestnut trees slowly give way to lush vegetation favoured by the humidity and the shade of the narrow channel of the stream, which runs through the quartzite rock. Ferns, mosses, lichens and trunks of water-loving trees, tapestry on the ground.

The mysterious and gloomy atmosphere accompanies the rustic wooden bridge that spans the stream and the legend of the Górgoras

Peña Infierna or Well of Gorgora. Once you have reached this bridge, the quiet walk along the crystal clear waters allows you to enjoy the uniqueness of this hidden and remote place.

The route begins at the Church of Manzanal del Puerto, at the foot of the Nacional VI where the Cosmological Stele is located, and runs through the town with a small cultural visit that includes the Peña de Santo Tirso and ends at the Casinas de Majar, which are testimonies of the agricultural past of the area.

You continue along a path, part of the Vía Nova until you reach the Valle de la Silva where you can hear the bubbling sound of its many waterfalls, among which is the Cascada de la Retuerta that gives this route its name.

Walking along the river bank, you reach the Ferrina Fountain, which owes its name to an old iron mine that is in the upper part and which is surrounded by a grove of centenary chestnut trees.

Following the route of the mining road we arrive in the town of La Silva, where you can visit the museum, which collects its mining past and its ancient workings.

After travelling to the past, we continue our way until we reach the ruins of the ancient Monastery of San Juan de Montealegre, originally known as San Martín de Montes ruled by the Military Order of Hospitallers of Jerusalem, a jewel of Romanesque architecture declared since the 90s as Asset of Cultural Interest by the Junta de Castilla y León.

Returning to La Silva, we will find remains of the mining activity that existed in the area for many years. Witness them in the extraction well and the personnel entrance crossing of the San Juan Well.

Between oaks, white hawthorn trees and meadows, the path back to the town runs in whose La Llama Park is exposed the Foundational Milestone of San Martín de Montes with epigraphs that prove its origin. We finish the route having a picnic in the Santa Bárbara Park, while we admire its mine entrance and its mining machinery.

It is a linear route of 5.8 km (one way). The route begins in Requejo where you can visit the hermitage of Santa José (18th century) and the church of Santa Eulalia (19th century).

Then, following the riverbed for a section and after a short climb, you will reach Peña del Moro viewpoint, with some interesting views of the area.

Advancing in an easterly direction about 600 m and on a spur on the slope of Cerro de San Bartolo, on the left bank of the Monterrequejo stream, you can see a settlement, the Castro de las Coronas, in which they have documented as the only delimitation system with a moat carved into the rock in the Northeast area, following which two large landslides can be seen that present a circular area and that could respond to a tower or similar, and a small embankment to the Southwest.

In this way, a small habitable surface is configured in which no material remains have been documented.

Then you will arrive at Corús, where you will find the hermitage of San Martín, a temple from the end of the 19th century.

Crossing the town on the right you can rest and quench your thirst in a source of fresh water.

Following the signposts of the route through wide oak bushes and rye fields, you reach Culebros where you can visit old irrigation wells, ending the route at the church of San Cipriano de Culebros from the 13th century.

There may also be (depending on the time of year) cattle grazing, so it is recommended to take special care not to approach or disturb the animals.

Among the vegetation that we find in this area, brooms, oaks, chestnut trees, cereal crops ... etc. dominate the landscape. There is a varied fauna such as wild boar, roe deer, wolf, fox, hare, eagle, cuckoo, lizard ... etc.

This route runs for 9 - 11 km, between the Brañuelas Town Hall and the “El Llastrón” forest in Villagatón, most of it parallel to the Muelas river along the rural road that runs from Brañuelas to Valbuena and also parallel to pine forests of which we can see two types: wild (from the middle and upper parts, they have an orange colour) and pinus pinaster (everything is the same dark colour, which is being resin).

Along it, you will see the ruins of 5 water mills, a resin mining area, mycological areas, two old town centers, strange caves drilled into the rock, a bee colony, the Villagatón Church, the Villagatón (empty) swamp. … and beautiful views from the mountains of several towns in the region.

It is a route of low difficulty, all of it between 1,000 and 1,125 meters of altitude, and special care must be taken when crossing the roads (twice, once in Brañuelas and another arriving in Villagatón) and the train track (Milestone No. 19, at  5.71 kilometres from the beginning). All of them are clearly signposted.

When leaving the road and approaching a mill, there may be water on the ground, so it is recommended to wear suitable footwear. Also, depending on the time of year, there are cattle grazing, so it is recommended to be especially careful and not approach or disturb the animals. Some of them, if they have young, can become violent in their eagerness to protect and defend their offspring.

There is a varied fauna in this area (another thing is that you will be able to see it!): Squirrels, rabbits, roe deer, foxes, wild boars, some wolves ..., as well as various types of birds, some more frequently than others: crows, kites, vultures, eagles, storks, partridges, quail...etc.

In addition to being able to do the route on the road (walking by bicycle or by 4x4 car), the most intrepid could do it by the river in summer: the landscape is splendid, but the difficulty is much higher, having to cross the river several times(wear high boots) and clear an obstacle.

The route signs are usually mostly on the right side, as well as off the road.
