Trekking in the Natural Park of the Hoces of the Duraton River

In the same foothills of the Natural Park of the Hoces of the Duratón River, perched on one of the first folds that it has been forced to draw, awaits the historic medieval town of Sepulveda, the start and end point of the Trail of the Two Rivers, a journey that will allow us to know part of the cultural heritage that this town treasures, while we discover the great natural value that since its first steps keep the Hoces of the Duratón River.​

Trail of the Two Rivers


The route through its 5.6 km draws a circular route transporting us almost in the time, thanks to the different corners that we will be visiting. Starting from the old church of Santiago, now the House of the Natural Park of the Hoces of the Duratón River, we will undertake a journey through the rich history of Sepulveda, visiting its old prison, the curious Main Square presided over by the remains of the old castle of the town in whose tower La Queda is still preserved, the name given to the old bell to whose replica the doors of the town were closed in the past. The route leads us along the wall to enter the heart of Sepulveda through the Ecce Homo Gate and to the church of the Virgen de la Peña, patron saint of the town. There we can approach to the wide viewpoint from where we will contemplate the capricious course of the Duratón River, besides we will be able to also descend to the hidden cave where the image of the Virgin appeared. A pleasant walk leads us out of Sepulveda to another of the seven gates of this town. The Gate of the Force precedes the descent that will take us to the meeting of the river following the route of the old Roman road that passed through here.

Duraton River

The Picazos Bridge not only allows us to cross the riverbed, but also marks the beginning of the path that runs along its right bank, a path that in a beautiful section runs along the vertical rock wall that surrounds the river. The old power station precedes our encounter with the route of the Trail of the Talcano Bridge and the Villaseca Bridge. Encounter that takes place next to the remains of Talcano Bridge. From here the route takes us back to Sepulveda allowing us to enjoy geological whims such as the Horse Saddle or the fold where the town sits, to go back into the old medieval enclosure after crossing the waters of the Caslilla River through the Gate of the Castro, or what is left of it. Ivy, ferns, the Virgin's shoes, the kingfisher, the blackbirds, plant and animal species that have chosen this unique habitat as their home, come to mind as we approach the Gate of Duruelo. Here we will have to say if we should extend the tour and visit, after crossing the Gate of the River, the old Arab quarter of Sepulveda before putting an end to the route or go directly to the House of the Park, crossing the district of San Andrés thus ending this Trail of the two rivers.

Hoces of the Duraton River


The Trick

If you prefer to go straight to the House of the Park from the Gate of Duruelo, but also want to know the Arab quarter and the Gate of the River. Or if you did not realise that you could continue the route by crossing the Gate of Duruelo and continuing under the cliff, and then going up it and entering this neighbourhood of Sepulveda, you have the option from the same road that passes by the House of the Park, to access this Arab quarter thanks to the ramp that goes down to it from there. You can also return from the Gate of the Force to Sepulveda directly if you do not want to go through the whole route. To do so, you only have to follow the asphalted track that leads to the Gate of the Force, a track that turns in a roundabout and leaving this old gate behind us brings us closer to the route of the conditioned Path of the Glorieta that allows us to return to the House of the Park.

How to get to Sepúlveda

Various roads lead to Sepulveda, such as the SG-232 which connects it with the nearby A-1 between Burgos and Madrid, at the level of the towns of Boceguillas and Castillejo de Mesleón on the one hand and with Turégano on the other. The SG-241 also reaches Sepúlveda, linking it with Peñafiel, among other towns, or the SG-V-2323, which runs through part of the Hoces of the Duratón river Natural Park. Without forgetting the various options available to us to reach Sepulveda from the N-110 in its section corresponding to the junction between Segovia and the A-1. Sepúlveda has regular bus service that connects it with Madrid, Boceguillas, Santo Tomé del Puerto, Segovia, Peñafiel and Aranda de Duero. Once there we will have to go into the town since the Casa del Parque will be found next to the old route of the road to Segovia, which has become one of the main roads in the town. Due to the difficulty of parking we will have several parking areas available at each entrance to Sepulveda.

Pet area, hiking with my dog

We are in a natural park with its own regulation which, although a priori does not make clear the obligation or not to take our dog on a leash, does advise us to do so. For the rest, and except for the urban sections we are before a route of ideal hiking to realize it with our dog.

We can not miss their corresponding ration of water, although certain areas of the river are easily accessible for our friend to quench his thirst. It would not be out of place to bring some food in case a pleasant lunch stop comes up.

This is an area of special ecological value and as such it has specific regulations that protect the flora and fauna that live here, although it is difficult for us to meet other animals face to face beyond the other pets that are in the area.


Description of the Trail of the Two Rivers

From the House of the Park to the Gate of the Force 2.1 km

The old church of Santiago, in Sepulveda, is home to the current House of the Park of the Hoces of the Duraton River (0h 00min), the starting and ending point of this trekking route.

We start the Trail of the Two Rivers in Sepulveda

We start the route descending to the road that runs through the town to go to the Spain Square.

We left the square on our right


As soon as we arrive, in front of us and between two historical buildings, we find the street where we have to continue leaving this wide square on our right.

We enter Sepulveda again

We then begin a rapid descent following the limits of the ancient wall of the town to find ourselves in the middle of a curve with the Gate of Ecce Homo, a gate that we must go through.

We don't leave the main street

We then begin to gain the lost height as we walk through the narrow streets of the historical centre of Sepulveda, without changing our course at the different crossroads that we encounter.

We reached the detour to the viewpoint of the Virgen de la Peña

Soon the buildings give way to a more open area where the silhouette of the church of the Virgen de la Peña can already be seen. Just before reaching it our route turns radically forcing us to decide between following it or taking a small detour that will take us to see this beautiful church and the magnificent viewpoint that awaits us right behind.

We continue to the viewpoint

Of course, we decided to go and see it, so after visiting it, we went to the viewpoint.

We reached the detour to the cave

A few meters before arriving we are offered another interesting option, to descend to the cave of the Virgen de la Peña, a short but demanding stretch that tempts us on our way.

We return to our route


After visiting the viewpoint and descending to the cave we will return on our steps to the crossroads we left behind before to resume the route we are following.

We left Sepulveda behind

Practically at the moment we will see each other outside Sepulveda following a conditioned walk. It is not too much to look back and contemplate the unique gorge on which this Segovian town is based.

We went out on a paved track

Our path takes us to a paved track that comes from Sepulveda and will take us to our next objective.

We arrived at the Gate of the Force.

We quickly leave the asphalt track to go to the nearby Gate of the Force (0h 40min), which we will cross.

From Gate of the Force to Talcano Bridge 1.6 km

We are approaching the Duraton River

After passing through the Gate of the Force we begin a rapid descent following the remains of the ancient Roman road that passed through here.

We arrived at the Picazos Bridge

This descent takes us to the very bank of the Duratón River, which is our companion for the stretch of route ahead.

We continue on the left

The Picazos Bridge serves us to save the riverbed, just to make it follow its descending course.

We follow the path at all times

From now on we will walk following a marked trail between the riverbed and the cliffs that mark it out. The vegetation almost does not let us contemplate the vertical rocky landscape that surrounds us.

We arrived at one of the most beautiful stretches of the route

Soon the relative comfort of the trail we follow disappears forcing us to face a hard stretch of ascent.

The hard spike comes to an end

Section that overcomes the unevenness that separates us from the path that runs in the middle of the vertical cliff that protects this bank of the river.

We're continuing by the cliff.

Luckily the steep slopes do not last long and once again we find ourselves moving forward comfortably enjoying the landscape thanks to the height gained.

We go back to the river

Soon after, the riverbank reclaims its protagonism and the path gently leads us back to it. Once again, the vegetation surrounds us, fitting us in between it and the rocky mass that rises above our heads.

We arrived at the Duratón River dam

Farther ahead, we came across the old dam on our left, which, among its functions, served to regulate the course of the Duratón River. The route continues without detours, approaching with every step the nearby bridge towards which we are heading.

We turn to go down to the Duratón River

Almost at the moment our route turns abruptly making us descend again in search of the Duratón riverbed.

We crossed the Duratón River

At the moment we find the bridge that will serve us to cross the river again, leaving on our right the path that leads downstream to the Villaseca Bridge crossing the endless meanders that the Duratón River draws on its way through these lands.

We follow the route along the old bridge

As soon as we cross the river, the old Talcano Bridge (1h 05min) awaits us, which we will not be able to cross due to its delicate state of conservation.

From Talcano Bridge to Gate of Duruelo 1.3 km

The current route skirts the bridge and undertakes another demanding climb, this time along a wide path.

We follow the main path

This is a path that we will not leave at any time and that little by little brings us closer to the parking area from where from the Path of the Talcano Bridge to the Villaseca Bridge begins, and whose route we will follow in this short section.

We continue on the left

Once we have crossed this parking area and before the road takes us out, our route forces us to say goodbye to it in order to set off for Sepulveda, but not before visiting a few more corners.

We go down to the Caslilla River

As soon as we climb the stairs that take us out of the way, a wide esplanade opens up before us, offering us a beautiful view and at the end of this esplanade, the continuation of the path that we must follow, which we can reach by crossing the esplanade or by following the path that borders it.

We follow the course of the river

A quick descent ahead of us will take us to the Palmarejos Bridge which will serve to cross the Caslilla River. As soon as we do so, the path turns, making us follow the descending riverbed.

We begin to ascend

A route that barely lasts a few meters since our path radically changes its orientation to undertake a new area of demanding ascent.

We arrived at the Castro Gate

Ahead of us lies a winding and somewhat stony ascent which, although not very long, does require a new effort.

End of this ascension zone

The Castro Gate or rather its remains next to those of the wall that protected this area, accompany us in this part of the route. After the effort and with our eyes already set on Sepulveda, we walk around the limits of the old fences that delimited these fields.

We follow the path on the right

The path seems to take us to the encounter with the road but, just before, it forks allowing us to follow it from the right and thus avoid the asphalt.

We arrived at the Gate of Duruelo

Almost without realizing it, we find ourselves before a new gate of the seven that Sepulveda had, the Gate of Duruelo (1h 40min).​

It's up to you to decide

Here we have two possibilities, to cross it and follow the path that borders the rocky outcrop on which the town sits, and then go up it to the Gate of the River where we will enter Sepulveda again, and from there climb up to the nearby church of Santiago, the House of the Park, from where we came out, or heeding to the signal and continue on our left without crossing the Gate of Duruelo.

From Gate of Duruelo to Park House 0.6 km

In any case, both routes are considered official, although from now on it will be easy for us not to find any more signs indicating the way to follow.

Another demanding ascent

If we decide to follow the indications of this crossroads, we will immediately start a new ascent that, after passing under the road, will leave us at the beginning of a staircase where we must follow.

We enter Sepulveda

This staircase ends when it meets the first houses in the town, leaving us already immersed in the urban layout, the end of the route. We continue to gain height, not without effort, surrounded by the buildings that populate this area of Sepulveda.

We hit the road

The street that we follow takes us directly to the encounter with the road that crosses the town, a road that we will follow.

We arrived at the House of the Natural Park of the Hoces of the Duraton River

This road, converted into Sepulveda street, takes us directly to the foot of the House of the Natural Park of the Hoces of the Duraton river (1h 50min), just where those who would have decided to follow the other possibility in the Gate of Duruelo and who arrive here after crossing the neighborhood of San Esteban, will join us to put an end to this hiking route.

Technical data sheet of the route

ico-distancia-totalDistance. 5.6Km

The different options we will encounter make this figure more than ever indicative.

ico-tiempo-totalTime. 1:50h

This time takes into account the possible detour to the viewpoint of the Virgen de la Peña and the descent to the cave, but even so can be extended or decreased significantly by the time spent in each place.

ico-calendarioTime of year

Although this is not initially the case, the park usually restricts access to certain areas during the first months of the year to encourage the breeding of the griffon vultures that live here. Otherwise, autumn and spring are ideal months for exploring the corners of this route. In summer the high temperatures invite to take advantage of the first hours of the day to enjoy this beautiful place.

ico-material Required equipment

A route that starts and ends in a tourist town such as Sepulveda, and which also has a stretch of its urban layout, may make us fall into the temptation of venturing along it without adequate clothing and equipment. With no fountains along much of the route, we cannot forget to take with us some water and food that we will undoubtedly need. Also some trekking or hiking sticks can be useful and help us in the ramps that we will have to overcome. Consult our list of material and equipment for hiking. Read more.


ico-dificultadDifficulty. Medium


We are going to face a not inconsiderable distance and a couple of ramps whose unevenness will test us, so being used to this kind of walks is essential so that the route does not become even more demanding. Be careful on hot days, it is advisable to avoid the hottest hours.

Severity of the environment

With the slippery ground because of the mud we can find quite slippery areas because of its slope. Otherwise in normal conditions, except for some bad tricks that play us the gravel of the paths and trails should not have major complications. However, we must not forget that we are between rocky outcrops and that in some sections we will advance next to them exposed to possible falls of stones. Pay attention to the urban route, it usually has a lot of traffic.


It is well signposted along almost the entire route, except for the urban route where some other signs are missing. Another area where we may have doubts is in the Gate of Duruelo as the map they give you in the House of the Park takes you to a place and the sign that indicates the route in the place indicates the other option of the two that initially can be followed there.

¿Did you know that...

The paths and trails that zigzag up the rocky slopes of the rocky canyon formed by the Duratón River resting on the stone walls are known in this area as Botaderas.

Don't miss out...

Sepulveda, although the route transports us through part of the history and cultural heritage of this medieval town, it is undoubtedly worthwhile for us to dedicate it, either at the beginning or at the end of the route, the time it deserves to get to know it in detail.
