The remains of a frenetic activity

In the middle of the mining basin in the council of Langreo, we find the Samuño Valley Path, between the towns of La Nueva and El Cadavíu station, a short distance from the centre of Ciañu, going through this valley along the route of an old mining railway. The characteristic natural landscape coexists with the traces left during more than a century by the mining activity carried out in the region.

Samuño Valley Path

The route with little more than 2Km follows the trench of one of the railroads that transported the coal extracted in the mines of the middle part of the valley, beginning in one of the main wells as it is the one of San Luis, that was active until the year 2001, becoming now part of the Mining Ecomuseum of the Valley of Samuño. From here we will descend through the valley following the path of the coal and enjoying the green landscape that hid, in its entrails, the black mineral. We will pass by population centres that grew under the protection of the mining activity surrounded by a leafy vegetation characteristic of the area such as chestnut trees, ferns and a great variety of species, which give their protagonism to small orchards.

Samuño Well

Halfway along the route we will be able to contemplate the facilities of the Samuño Well, in addition to the large number of wells that the region had active years ago. From here and almost without realizing it, we will arrive at the El Cadavíu station, now a centre for the interpretation and reception of visitors to the Mining Ecomuseum, where the route ends.

The Trick

We can leave our vehicle in the car park of the station of El Cadavíu from where the visit to the Mining Ecomuseum leaves, and after making this guided visit, descend by the Samuño Valley Path until the station.

Mining Ecomuseum Train

How to get to Samuño Valley

We can reach Langreo by following the AS-1 that joins Mieres with Gijón and taking the exit towards Langreo, which we will reach via the AS-17, this same road on its other side communicates the town with San Martín del Rey Aurelio and Pola de Laviana, entering the heart of the Redes Natural Park, passing through Ciañu, close to Langreo, where we will find the detour towards La Nueva that will take us to El Cadavíu station. In this place is the reception centre for visitors to the Mining Ecomuseum and it is where, if we visit the museum, we have to leave our vehicle. If we continue along the road, it will take us to La Nueva, just 2 km away, where the Pozo San Luis is located.

​​Pet area, hiking with my dog

A short stretch of asphalt, a short stretch of road and a couple of junctions are the biggest complications we will find.

In the initial zone we have a fountain, although the short distance of the journey and the shady of it does not cause problems.

Special attention we have to have with the farm animals chickens and goats fundamentally that we will find very habitually in the route.

Description of the Samuño Valley Path

From San Luis Well to The Cadavíu Station

We begin the route next to the main entrance to Well San Luis (0h 00min), from here a wide lane shared with bicycles leads us in an almost imperceptible descent towards the lower part of the valley.

Initial place of the tour

Leaving behind a small recreational area and some paths that serve as access to the houses and orchards that border the itinerary, we will continue along this asphalted and well signposted lane until we reach the height of Samuño Well (0h 15min).​

El camino está en muy buen estado

Once here we will find a short but steep ramp.

A steep slope

The ramp, fitted out with stairs, quickly descends towards an underground passageway, but shortly before reaching it, the lane that brought us here begins again on our left, and where we must continue.

We turn to the left leaving the ramp

Little by little we are moving away from the old mining well, the nearby road separates us from the train trench that leads to the interior of San Luis Well.

End of the conditioned lane

We arrive at the end of the conditioned lane that is with a road that crosses it, in this place we can continue for her or to continue straight for a small path that forced us to descend the slope that saves the difference of height with the road.

The road on the left goes down directly to El Cadavíu, the one on the right takes us through the forest.

Once again we will have to decide whether to continue along the road, descending the scarce 200 m that separates us from the station of El Cadavíu or ascending along the one on the right, cut by two large stones, to continue the route along a beautiful path.

The trail starts to the left of the esplanade

After passing the boulders we will arrive at a wide esplanade that apparently housed some pavilions, following by the left margin next to the limit of the vegetation we will find a narrow footpath made of stones that borders all the esplanade.

The trail enters the forest, we follow the white and yellow marks

At the end this path turns left into the lush forest, the trail inside remains conditioned with this layer of boulders.

We leave the forest and descend towards the road

Among the vegetation, on our left, we can sense the station building that we will leave behind us, this fact and the fact that the route no longer has the same paved road as the previous section may make us think that we have been confused and that we follow a path that takes us to another place.

We turned round to go to The Cadavíu

Just out of the forest we will see a green ramp that descends a few meters, just at the end of this ramp the route turns radically back to direct us to the Station of The Cadavíu (0h 35min) to which we will arrive after crossing the road again.

ico-dificultadDifficulty. Low


Wit:practically no physical demands, it is a pleasant walk, where only the ramp next to the Samuño Well and the final part of the pat:inside the forest suppose an effort if we make the route in ascending sense.


Most of the route is by an asphalted track and the area of pat:throug:the interior of the forest can be replaced by a short stretc:of road. You will have to pay attention to the crossroads and the section of road, if you continue along it. The part of the trail throug:the forest is conditioned wit:a layer of stones that facilitates the passage.


Perfectly signposted and well defined the route will not have problems in following it, at most we can think that we have been confused if we follow in the final part the pat:throug:the forest and that at first moves away from the building of the station.
