The hillsides of the mountains that make up the Sierra of Urbión hide spectacular places that seem to have been taken from science fiction films, together with small corners full of magic and serenity. Not too far from Duruelo de la Sierra, hidden by the thick forest that populates this area of Soria, under the protection of the Urbión Peaks, Castroviejo and Cave Serena await us, two of the unique spaces that we can find in this region.
The 2 km route can well be doubled, partly thanks to the labyrinthine scenery we find in Castroviejo. Rocks with curious formations, shaped over the years by the expert hand of nature, canyons and cavities through which hardly a person passes, hardened and strong trees that are born from the same rock crowning in solitude the enormous formations that form this natural space of great value, both landscape and natural. The route transports us through this beautiful environment allowing us to wander around it, discovering every corner of it. We descend surprisingly with each step we take without imagining the spectacular panorama that awaits us on the edge of this place, where the Castroviejo Viewpoint awaits us, from which we can contemplate the entire length of the newly born Duero Valley and the different villages that make it up.
From here and returning to the parking area of Castroviejo, from where we started, we will set out for the next jewel, which we will visit, following the wide dirt track that continues along the road we arrived at. A quick and short descent will bring us to the beginning of a wide path that, on our right, ascends without delay to the nearby Serena Cave. There, a special corner full of beauty awaits us, surrounded by the peace and quiet provided by the sound of water falling from the top of the cave, the whimsical luminosity that gives it an almost magical air and the exuberant plant and animal life that surrounds it. A cave, a refuge for animals, that surprises as much as it does from the outside as once it is inside. After having enjoyed this whim of nature we can only say goodbye to it, not without sorrow, to return following our steps to the parking lot of Castroviejo, the starting point of our tour.
To get to Duruelo de la Sierra we have to follow the CL-117 road that from Salas de los Infantes crosses the Sierra of Urbión from one end to the other, rejoining the N-234 in the town of Abejar, the national road that connects Soria with Burgos. In this same section of the national road we will find several accesses that also communicate with the CL-117. At the same time, from the northern side of the mountain range, there are two roads, one coming from Neila and the other from La Rioja, passing through Montenegro de Cameros and Vinuesa. Once there, just at the entrance of Duruelo de la Sierra, as we arrive from Covaleda, we will find the asphalted road that, well signposted, gives access to Castroviejo. We will only have to cover the barely 7 km that in frank ascent, and without more detours, separates the town from this place. Once there, we will have a large car park where we can park our vehicle.
This figure will increase as we walk through the Castroviejo labyrinth.
The final time must be marked without a doubt, not what it costs us to cover the distance between one point and another, but on the contrary, what we entertain ourselves in each place.
Except when the snow or ice prevents us from accessing, we can reach Castroviejo itself with our private vehicle throughout the year and enjoy the different singularities that each period brings to the already imposing place. While in winter conditions this area is difficult to access and is reserved for a more experienced public in these conditions.
Always starting from good weather conditions, we are in front of a real walk that does not require big equipment or backpacks, but we cannot forget that we are at more than 1500 m of altitude and we go through a changing natural environment. Of course the camera will be a good companion. Consult our list of material and equipment for hiking. Read more.
Except for the short ramps that we will have to save along the route we will not find major obstacles that require a great physical condition to enjoy both places.
Severity of the environment
As long as we follow the main trails in Castroviejo and don't venture up onto the rocks or look for hiding places or passages between them, we don't face any complications except for a few slips in the gravel on the trail. Do not underestimate the area as the rocky cuts and hidden cavities can play a trick on you. In Serena Cave it is the humidity of the ground that can give us some kind of scare. It goes without saying that it is not very advisable to try to climb the rocky outcrop, or rather to do so in order to get a view of the cave from its edge.
With well signposted routes and perfectly defined tracks and trails this section should not be a headache for almost anyone, except if we venture into the maze of rocks in which case we can get lost.
