Surrounded by imposing mountains and steep ravines, which pour their waters into the newborn river Aragon Subordan in the heart of the Natural Park of the Western Valleys and belonging to the municipality of Ansó, awaits us the majestic setting of Tuertas Waters. History and nature merge in this place marked by the whimsical course of the river as it flows through this wide plateau nestled between mountains, chosen by the ancients to leave us enigmatic evidence of their presence here.
The route with only 6.8 km starts from the parking of the Ravine of the Barcal to go up the valley of Tuertas Waters to which to its natural value must be added that of having one of the greater concentrations of megalithic constructions of all the peninsula. The Mallo Blanco breaks with the peaceful landscape of the valley through which the Aragon Subordan River flows, trying to escape from the mountains that saw its birth. We gain height as we contemplate closer and closer The Jump, a deep gorge that cuts the side of the mountain and through which the river rushes from the top of the plain towards which we are heading. As we pass by, we almost do not notice it, either because of the distance that separates us from them or because we need to know how to distinguish some of these mysterious constructions. We will leave behind different megalithic mounds that are over 4500 years old, true jewels of history.
The hut of Achar of Tuertas Waters receives us after a not little demanding ascent following the steps of the GR 11 in its advance by this zone of The Pyrenees. The extensive high plateau of Tuertas Waters extends majestically before us, allowing us to contemplate the twisted riverbed as it passes by. Many people have passed through here, livestock farmers, traders, bandits and now mountaineers and hikers who never cease to be surprised by the landscape around them. However, there are few people who have such a longstanding record of their presence in these lands as the millenary stones of the Dolmen of Achar of Tuertas Waters bear witness to. Once we have enjoyed the magical harmony that this place transmits, we will take the road back following our steps to return to the parking lot, from where we set off on this interesting route.
To get to Tuertas Waters we must first go to Hecho and Siresa from Puente la Reina de Jaca, on the road that connects Pamplona with Jaca and which can also be reached from Huesca. Or from Ansó following the road that links the valleys of Hecho and Ansó with the Roncal valley in Navarre. Once in Hecho we will have to head towards Siresa and continue without deviating from the road that passes through this town up the course of the Aragon Subordan River, crossing the narrow Ravine of the Mouth of Hell. Without leaving the road we will arrive at the Oza Forest where we will continue without deviations the battered road that little by little is becoming an ample earth track that goes up all the valley taking us until the zone of parking located where the authorization for the circulation of vehicles finalizes and where we will be able to park ours and to begin the route.
The torrent of water that flows through the Barcal ravine marks the end point of the permit for the circulation of vehicles on the track that goes up the valley.
Right there, from the parking lot (0h 00min) that is located in this place, the route starts that will take us to the extensive plain of Tuertas Waters.
Thanks to a small bridge we will be able to cross without getting wet the water flow that goes down to the river.
The wide dirt track we came here on continues to guide us to our destination. We go up the valley gaining height calmly but without pause.
The landscape that surrounds us makes this long stretch of path that awaits us much more enjoyable.
Soon we will begin to contemplate the head of the valley where the water jumps, escaping from it.
After a while of calm ascent we will find another water torrent, normally dry, but that in certain times of the year can descend with enough water.
We arrived at the moment of choosing between following the course of the track that winds up, ascending the slope of the mountain. Or do it by the path that shortens the route in exchange for a greater effort.
The stony trail coincides with the route followed by the GR 11 as it passes through this area.
We will soon find ourselves back on the path that offers us its long and more tranquil itinerary.
On the contrary, our trail, after crossing it, continues with its convoluted and demanding course. The typical milestones and marks of the GR serve as a reference to follow.
There are several trails that cross this hillside, in search for the most comfortable route for each person.
Almost at the top we'll have to go through a gate that stops the cattle. We only have a short stretch of ascent left that will take us back to the path just as it reaches its end.
The hut of Tuertas Waters and its enclosure marks the closeness of our objective.
Now we will only have to decide whether to descend directly or continue for a while the route of the GR to go up the plain, without having to overcome hidden channels or waterlogged areas.
Along the GR we will have several possibilities to say goodbye to it and to descend to Tuertas Waters (1h 05min). If this has been the chosen option, for our return it is better to do it following the same route until the proximities of the cabin.
There we can return to the plain to approach another of the magical corners of this place. An almost unappreciable trail borders the hill that marks out the hut leading us without any problem to the Achar Dolmen, Tuertas Waters (1h 10min).
After dedicating the time that this beautiful place of the Pyrenees of Huesca deserves we will return desandando the walked thing until the parking (1h 50min), where we initiated this route of hiking.
The route we follow on the Agua Tuerta plateau will mark the final distance.
Without a doubt, it is worth dedicating enough time to this natural spot to enjoy the spectacular landscape it offers together with the calm and tranquillity it transmits and not to go up and down in a hurry.
In periods when snow and ice are not the protagonists, besides simplifying notably the difficulty of the route, they will allow us to enjoy one of the beautiful corners that the Valles Occidentales Natural Park treasures. The intense colours of spring and autumn give added value to the curious landscape that awaits us in Tuertas Waters, covered in snow in winter. The water is one of the protagonists of this route and its presence or not also alters the beauty of the place and the difficulty to access it, since there are several streams that pass by.
No matter how simple or easy a route may seem to us, it is always advisable to take a minimum of equipment in addition to suitable footwear and clothing, in this case of hiking. A windbreaker, waterproof or warm clothing that gives us some margin if we need it, some food and water in addition to the usual protection against the sun, a small first aid kit and the necessary equipment that together with the information of the route will help us to orientate ourselves in case of doubt or need, are some of the companions that should never be missing. Consult our list of material and equipment for hiking. Read more.
The unevenness we will have to face is largely concentrated in the vicinity of Tuertas Waters. There we will face hard ramps that if we take them with patience would not have to cause us major complications. Given the total distance and having enough time to take it easy, we will be facing a route that will not require us a great physical preparation.
Severity of the environment
Under normal conditions, in summer, and as long as we do not leave the route as planned, we should not have any complications, always bearing in mind that the natural environment around us is uncontrollable and changing. The trail that goes up to Tuertas Waters is a little broken, also crosses a threatening scree zone while gaining height, this area along with the short stretches of track in which we cross the streams, in many cases without flow, are where we will be more exposed although we do not seem so. Be careful if you go through the Tuertas Waters meadow, it is a labyrinth of hidden watercourses that feed the main river.
To get there and back we should not have any major difficulties since first the wide track and then the marked path will guide us perfectly. The marks of the GR-11, which we will coincide with in the area of Tuertas Waters, should not confuse us, although in the area of the trail they will be of great help in guiding us through the network of trails that cross the stony slope. Once in Tuertas Waters we will only find the marks of the GR 11 that crosses the side of the valley, so it is important to be aware of the possibility of fog. We will have to have clear in advance where the dolmen is located if we want to go see it.

¿Did you know that...
The megalithic heritage of the province of Huesca is one of the most important and extensive in the entire Iberian Peninsula. These rupestrian sanctuaries form an important part of the prehistory that has reached our days, contributing its enigmatic and in many cases unknown story to the fabulous landscape that surrounds them.
Don't miss out...
The Dolmen of the Pass of Escalé is about 2 km away at the bottom of the Tuertas Waters Valley, at the crossroads with the path that leads to France. It is an interesting megalith that stands out for its unique interior structure, more complex, which makes it almost unique in the Pyrenees.
