Through the Path of the Arrudos to the Lake Ubales

The Redes Natural Park has great natural wonders criss-crossed by hiking routes that are imposing and beautiful, almost in equal parts. One of the most fascinating itineraries in Redes and Asturias is perhaps the route of the Gorge of Arrudos and Lake Ubales. A path that takes us through lush beech forests, green meadows and an impressive limestone gorge where water is one of the protagonists. This adventure can be said to consist of several sections, a short route that takes us to La Fontona or Fuentona, another long route that climbs up to Lake Ubales and there is even the option of a circular route that takes us to the village of La Infiesta, but from there we will still have about 5Km by road to return to Caleao, our usual starting point.

How to get to Gorge of Los Arrudos

To find the starting point of the Gorge of the Arrudos route we have to go to the Asturian village of Caleao. To get to Caleao we have to follow the road which joins Pola de Laviana with the Port of Tarna, on the border with the province of León. It is at Coballes, at the head of the Tanes reservoir, where the road leading to Caleao awaits us. Once there we have the option of parking our vehicle in the village itself or just before arriving we can take the turning which leads to the nearby Hermitage of San Antonio where we can also park and begin our route.​

Itinerary of the route of the Gorge of Arrudos and Lake Ubales

From Caleao to The Fontona 6,2 Km

If our starting point is the village of Caleao we will have to follow part of the road by which we arrived to take the detour that leads to the Hermitage of San Antonio. Our route is marked by the indications of the PR-AS 61 la Path of the Arrudos. Once at the hermitage we must continue walking along the track, going up the stream of the Arrudos. Soon the green meadows take us to the stream bed, which we cross several times to reach the renovated Corones Mill. The slope begins to become more evident, making us gain altitude in exchange for some beautiful views. The Aguamayo fountain, one of the different fountains we will pass, invites us to take a break along the way to replenish the energy we have spent.

Our track gradually leads us into a beautiful beech forest as we follow the capricious flow of the Arrudos stream. The Fuminosa bridge marks the beginning of a beautiful and demanding stretch of our route that runs between the walls of the mountains that mark it.

A stretch that takes us to the green meadows of Majada de Prendoriu. These meadows are just a beautiful mirage as our path quickly leads us back to another gorge. The Calabaza bridge marks the true beginning of the Gorge of Los Arrudos, surely the most spectacular stretch of the whole route. After crossing the bridge we begin a tough climb up the stairs carved into the rocks of the walls that delimit the gorge. These stairs alternate with less demanding stretches of cobbled path. Another wooden bridge allows us to cross the stream bed again to begin another demanding ascent along the characteristic stairs carved into the rock of the Gorge of Los Arrudos route. After overcoming this beautiful and demanding stretch we reach El Collaín, where this part of the ascent ends. Not far from there we reach La Fontona (2h 30min), which we reach by crossing a small wooden bridge.

From La Fontona to Lake Ubales 7.1 Km

Many people put an end to their route through the Gorge of Arrudos here, retracing their steps back to Caleao. If you are still feeling energetic you can continue the route to Lake Ubales following the signs for the PR-AS 61 la Path of the Arrudos. The path forces us to continue ascending, entering the beech forest of Los Arreballaos. A beautiful stretch that takes us to the Roxecu sheepfold, where the remains of the old huts that once stood here await us. We cross the stream that gives it its name to begin the ascent that separates us from the Llede and Moyones sheepfolds. The landscape has changed, allowing us to contemplate the mountains that surround us. In the distance we can already see the Ubales pass towards which we are heading. It is not without effort that we reach this mountain pass that offers us an unbeatable panoramic view. After recovering some energy we continue the route following the path that ascends the slope of Peak Cascayón. Luckily we soon begin a downhill stretch that brings us to the beautiful Lake Ubales (5h 00min), where we enjoy a well-deserved rest.

From Lake Ubales to La Infiesta 9,2 Km

After enjoying this spectacular spot in the Redes Natural Park, we must return to the Ubales pass. Once there, we will have to decide whether to head towards Caleao, retracing our steps so far, or to head towards La Infiesta, thus making a circular route. If this is the case, we will start to descend the opposite side of the pass in search of the Carbaza sheepfold, where we will join the old route of the Camín de Castilla. The path turns to the left, taking us to the opposite slope of the mountain we are crossing. We then begin the ascent that will take us up to the Collada de la Canalina, whose gradient has nothing to do with the ramps we have already overcome. The path that we are following makes us lose some height again and once again forces us to make a new effort that brings us closer to Pandu Vallegu. From there we only have to resume the long descent, sometimes quite steep, that will take us to the pretty village of La Infiesta (7h 00min), where this PR-AS 61 la Path of the Arrudos ends. Once in the village we must return to Caleao following the approximately 5 km of road that separates it from La Infiesta, which is in addition to what we have done so far.
