The route begins in the Winter Park, one of the great green lungs of Oviedo/Uviéu, where the vegetation is already beginning to announce the transition towards an increasingly rural environment. Among the trees that accompany us are hazelnut trees, hackberry trees, birches and holm oaks, and it is not unusual to hear or see birds such as mallards, woodpeckers and goldcrests, among other forest species.
The path follows the route of the old railway line that connected Oviedo/Uviéu with Uxo and San Esteban, which was converted into a greenway after the closure of the line in 1999. Along the first section, we cross under the motorway several times, and shortly after we reach the old La Manjoya train station, with the Mostayal peak looming on the horizon.

The route continues through old railway tunnels, among which the most important are:

El Molineru (150 metres long).
El Mergallu (70 metres).
Premaña (30 metres).
Veneros, the longest, at 260 metres.

Between the tunnels, the landscape continues to evolve towards more open areas, where meadows and riverside woods accompany the walker. In the intermediate stretch you can also see old mills, vestiges of the agricultural and industrial activity of the area.

The path takes us to the old Fuso Station, where we can see the centenary iron bridge over the river Nalón and Peña Avis on the horizon. From here, the route links up with the Senda Ribera del Nalón, crossing the river on a pedestrian footbridge to continue along the banks of the Nalón until we reach Les Caldes.

This last stretch of riverbank, included in the Natura 2000 Network, allows you to enjoy a natural environment of great ecological value before reaching the Royal Spa of Las Caldas, an old bathhouse from the 18th century, an example of the thermal past and the tradition of medicinal waters in the area.

The return journey can be made along the same path or, if you prefer, using public transport from Les Caldes. This path is a perfect option for those who are looking for a comfortable route, without steep gradients, combining nature, history and railway heritage, with the added attraction of covering, in just a few kilometres, the route from the city to the tranquillity of the riverside.

  • The route crosses perpendicularly with the GR-106.

Basic tips before going into the mountains

  • Avoid approaching livestock.
  • If you find mastiffs protecting livestock, do not approach them, do not pet them and do not feed them. Do not allow them to follow you or stray from their herd. They are working.
  • If you go with a dog, always keep it on a leash.
  • Don't leave a trail. Collect all your waste, including organic waste. Nature is not a dumping ground.
  • Act with prudence. Plan your route well, take everything you need and make sure it is adapted to your physical capacity.
