Located in the municipalities of Muriel de la Fuente and Cabrejas del Pinar, the Natural Monument of La Fuentona of Muriel, in Soria, is immersed in one of the largest and best preserved sabinares in the Iberian Peninsula. Undoubtedly, the limestone moor on which it stands has contributed significantly to the process of creating the unique landscape that characterizes this region, making it an ideal habitat for various species of both plants and animals.
This route of hiking with hardly 3,2 km enters us from the same doors of Muriel de la Fuente, where the zone of parking is located, until the same birth of the Abión river that arises from the bowels of the earth in La Fuentona. We will follow a pleasant walk that will allow us to cross the first meters of this river surrounded by the thick vegetation that characterizes this region and under the attentive look of the tireless griffon vultures that populate the vertical cliffs that mark the valley that we are going up. Cliffs and rocks full of life, like the one that opens its way taking advantage of the cracks and fissures they find there. Cracks and fissures that channel rainwater, filtering it into the very interior of the earth, eroding it and creating a complex hydrological network that ends up forming the Cabrejas aquifer. This network is composed of at least one gallery yet to be fully explored and in which speleodivers have already submerged to at least 100m.
It is linked to another large cave full of torrents of water and cavities, some of which are up to 80 metres long, and this large cavity is in turn linked to a huge siphon 54 metres deep and more than 200 metres long from which La Fuentona or the Eye of the Sea, as it is also known, emerges on the surface. A subterranean world hidden from our eyes but that gives us all the special landscape that surrounds La Fuentona, gateway to the unknown. But the uniqueness of this natural place does not end here, to the junipers and rocks joins the Waterfall of La Hoz or La Fuentona. This is a spectacular waterfall that, with some luck, we can see almost from its base, as long as the generally dry riverbed of the La Hoz stream presents us with its presence. A natural monument that will undoubtedly envelop us with its beauty, making it more difficult to say goodbye to it and return to the hermitage of the Virgin of the Valley, from where we started.
According to the legend, the deepest part of La Fuentona is inhabited by Las Ondinas, mythological beings that bewitch with their songs those who dare to lean out of the crystalline waters of the Eye of the Sea in search of the entrance to the mysterious world in which they live. A world to which they drag everyone who insists on trying to discover the hidden entrance under the cold crystalline waters.
To get to La Fuentona, we must follow the SO-P-5026 road, which starts 25 km from Soria on the N-122, between this road and El Burgo de Osma, and after passing through Calatañazor, we reach the gates of Muriel de la Fuente. This same road leads to Muriel de la Fuente, but in the other direction, it connects the town with the towns of Muriel Viejo and Cubilla. Once there and just after passing the bridge over the river Abión, just before entering Muriel de la Fuente always, of course, if we arrive from Calatañazor, we will find the track that takes us to the different regulated car parks that this natural monument has. There is also a small parking area at the foot of the road.

Although in principle there are no clear rules requiring us to keep our dog on a leash, we are advised to keep them under control, that is, to use common sense. On the other hand, we can find a lot of people with their vehicles, so we have to be careful.
There are no areas where you can drink without having to go near the river, so it is not too much trouble to bring some water even if we are on a short route.
Surely there will be several pets that we have to go to meet, while the local fauna will be more difficult to see, except for birds that fly over us almost at all times.
This route has been carried out on the ground by SENDITUR on 25-04-2017.

The car park (0h 00min) at the foot of the hermitage of the Virgen of the Valley, a short distance from the road where we arrived here, is our starting point for this interesting and simple route.
The wide track that leads to the next parking lot serves us, under the attentive eye of the hermitage, of unbeatable route to enter this natural monument. The river Abión will accompany us on this walk to La Fuentona.
We leave on our right a long footbridge that crosses it, where the path that comes from the house in the park reaches here, on the other side of the road where we arrived.
Without almost noticing it, we will find ourselves in front of the old , and its corresponding parking area.
It is right here where the real adapted tour begins that will lead us to our unique goal. A wooden footbridge is now in charge of leading us smoothly through this natural space.
After passing this first rocky area, a tree-lined walk opens up before us, leading us to a new footbridge through which we will cross the riverbed.
The gentle undulation of the terrain in this part of the route is how many complications we should encounter along the way.
Soon after, we reached another bridge that marks the beginning of the trail that, if followed, would take us to the La Hoz stream waterfall. We left this detour to the waterfall (0h 25min) behind for the moment and continued on our way, crossing the conditioned little bridge.
Not much further ahead, among the vegetation that surrounds our route, the silhouette of La Fuentona of Muriel (0h 30min) emerges, the place where the route ends.
Once we have enjoyed the spectacular landscape that this natural treasure offers, we must return following the same itinerary that brought us here.
Of course we have the opportunity to approach, once crossed the bridge, to the peculiar waterfall of La Hoz. To do so, we will only have to follow the quiet path, which, without any conditioning, will lead us to it.
This trail crosses the leafy forest of this part of Soria without any major complications. The flow of the stream, which we will cross, helps us to predict the state in which we will find the waterfall.
Sooner than we had probably imagined, we reached the abrupt end of the trail, right at the foot of this whimsical waterfall, although to see it properly we will have to climb up on the rocks that cut our path or descend to the usually dry stream bed.
After contemplating the enormous and vertical walls that surround us, we will return until the beginning of the path to retake the course of the walkway that will take us back to the information booth and from there to the beginning of this route of La Fuentona of Muriel.

Total distance. 3,2 Km
Total time. 1h 00min
This is the approximate time it will take us to do the route without going near the waterfall. If we dare to visit it we will have to add about 20 minutes which is how long it should take us to do it.
Time of year. A wonder all year round
The winters in this area are hard, and can undoubtedly condition our visit, but also offer us a privileged picture, while the rest of the year gives us a pleasant walk that the flow of the river with the colorful state of vegetation around us will highlight even more if possible. Unfortunately, the periods in which we can find the waterfall with water are reduced to a few days a year.
Required equipment. At least one pair of comfortable or sports shoes
Although the route is perfectly conditioned and we should not find ourselves with difficulties typical of larger routes, it is not too much to use a shoe that gives us greater functionality for land like those we are going to tread. To immortalize our passage by this place with a few photographies next to not forgetting to take something of water, generally are as many preoccupations to us, however we must not forget that we are in the natural enviroment, and that we will have to adapt us according to the moment that we choose to make this route. Consult our list of material and equipment for hiking. Read more.
Slope acumulate. 80 m Slope positive. 40 m Slope negative. 40 m
With hardly any distance and a minimum unevenness, the only thing that stands out is the inclination of one of the few ramps that we pass, something more evident and that in these cases will require us to make a greater effort.
Severity of the environment
Taking into account the regulation that affects the area and that recommends and prohibits leaving the route, we should not have to face complications in this section. Being in the section that leads to the waterfall where something more abrupt we have to find the land. It is true that certain sections run at the foot of the rocky slope, somewhat exposed to possible landslides. Needless to say, bathing is totally forbidden.
Given the perfect condition of the route, following it does not pose any complications, in addition to the different marks and indications that we will find. In La Fuentona the adapted route ends but not the short distance path with which we share our course and which should not be confused with its marks and indications.
