The little known Well of Airon


The town of Pereña de la Ribera in Salamanca, one of the gateways to the famous Well of the Fumes, holds some of the most spectacular places of all those that make up the Arribes del Duero Natural Park. One of these charming corners is the Well of Airón, less known than its renowned neighbor but with a great attraction to discover.

Well of Airón



The route with 2.8 km, provided that we leave from the parking area located at the end of the road that comes from Pereña de la Ribera, transports us through this exceptional natural place. A natural place that has been part, and forms part, not only of the splendid nature that composes it, but also of the people who live and inhabited these lands as the remains of the mills we have to pass by testify. A nature that surely has to surprise us with the nourished life that shows to our step, jinetas, foxes or alimoches are only some of the species that inhabit the place coexisting with the thick vegetation that grows in these hillsides.

Well of Airón

But if there is something that should surprise us on this route, it is undoubtedly the Well of Airón, a spectacular waterfall almost equally full of mysticism and beauty. A beauty and an aura of mystery to which the possibility of accessing the interior of the cave that the erosion has carved behind the curtain of water that falls into the void from the top of the ravine contributes significantly. These attributes make this place a must if we are visiting the Arribes del Duero Natural Park.

The Legend


The local people say that many people have disappeared since time immemorial. Legend or reality, they say that the Well of Airón hides in its interior the sinister entrance to the underworld and that it is guarded by a capricious god of the waters, the wells and the depths. Everyone who enters its interior is observed by this god of the underworld who is capable of creating life with the waters he dominates, but also of taking possession of the souls to lead them, without possible return, if he so decides, to the other world whose entrance he guards.



How to get to




We reach Pereña de la Ribera by following the road that connects it with the town of Trabanca. This same road also connects it with Masueco, which can be reached from Vitigudino by following the SA-314 or from the nearby Mieza and La Zarza de Pumadera. Once in Pereña de la Ribera we will find the pertinent signs that will guide us to the parking area set up at the beginning of the path. The path that leads to it is usually in relatively good condition, although it is not unusual to pass some areas that are somewhat decomposed due to the torrents that are formed on rainy days.

Pet area, hiking with my dog



Quiet route for our dog, as long as he is used to this type of route.

It is not superfluous to bring him some water, although if the river allows it in the Pozo de Airón he will be able to drink as much as he needs.

It is quite likely that we will find some cattle grazing in the area, also we must not forget that we are in the Natural Park of Arribes de Duero and that it has its relevant legislation to follow.









Description of the route of the Well of Airón


After the long journey on the dusty track that has brought us from Pereña de la Ribera to here, the short parking area (0h 00min) where it ends, marks the beginning of our route.

We start the route in the parking lot of the Well of Airón



A wide path, which seems more like the battered continuation of the road, allows us to advance without major problems.

The path begins

Almost immediately we come across the beginning of the trail that will take us to the Well of Airón.

We follow the trail at all times

In this section the route follows a well trodden trail without too much slope, letting us intuit, on our left, the course of the creek that falls into the void later on.

The route is not very difficult

As we advance along the trail, the vegetation allows us to contemplate the stream and its whimsical course in more detail. We will come across small bends that we can approach to take a careful look at some of the small waterfalls that the stream makes in this part of its course.

The section with the greatest slope begins

In front of us, the valley we are walking through gradually opens up, advancing relentlessly towards its union with the mighty Duero, which hides from our gaze behind the walls that imprison it. We then begin a rapid descent that will make us lose height quickly.

We lose height quickly

The trail winds repeatedly through the dense vegetation that populates these mountains. A zigzagging that allows us to contemplate in the distance the path that approaches the solitary viewpoint that can be perceived on the horizon. At the same time, the majestic presence of the Well of Airón, which we can already see, imposes itself on the surrounding landscape.

We detour to the Well of Airon



After a while we arrive at the detour we must take, radically changing our course and saying goodbye to the path that continues towards the distant viewpoint. A short stretch awaits us in front, while we enjoy the Well of Airón (0h 30min) which we quickly reach.

We arrived at the Well of Airón

The only thing left to do is to enjoy the place, go inside the waterfall, if the flow and the slippery stones allow it, and go back to the car park (1h 15min) from where we started.

Technical data sheet of the route



Total distance. 2,8 Km


Total time. 1h 15min

The return will be the stretch that will take us the longest to cover since we will have to face almost all the positive slope of the route.


Time of year. Attention to the river floods

As with all the waterfalls, the flow of water will partly determine the beauty and interest of the route. It is important to realize that when you access the waterfall you are in the middle of the flow of water that descends through the ravine, a fact that may advise against entering it due to the danger it may have.


Required equipment. Keeping an eye on the heat

On hot days it is important not to leave the water behind as we must not find sources on the way and the sensation of heat can be intense. As always we must adapt our equipment to the route and the time of year in which we venture to walk it and of course not try to do it with unsuitable shoes or poorly equipped because although it is a simple route we must not forget where we are. Consult our list of material and equipment for hiking. Read more.




Slope acumulate. 360 m   Slope positive. 180 m   Slope negative. 180 m


Difficulty. Medium



Without a great distance to travel, this trail accumulates in a short distance almost all the unevenness to overcome. For this reason it is important to take the ramps that we will find with a certain calm and not to harden the route without necessity.


Severity of the environment

As long as we do not abandon the path, we should not encounter any complications other than the stony nature of some areas, concentrated in its final stretch. Be very careful if you approach the bed of the creek, as it is usually nestled between vertical walls. Another point to pay attention to is the Well of Airón, here both its flow and the slippery stones that we will have to cross to approach its interior can play a trick on us.



A perfectly defined path will be in charge of guiding us on this trekking route in the province of Salamanca. In addition we will have the invaluable help of some marks that will guide us at the beginning. The almost total lack of crossroads with other paths or trails also facilitates the task, we will only have to be attentive and almost in the Well of Airón to divert to it and not follow the path that would lead us in a first term to a beautiful viewpoint.

El Pozo de los Humos es el más conocido de esta zona pero este Pozo de Airón también es muy bonito y está mucho menos masificado que el otro.

¿Did you know that...


A little further on from where the Pozo de Airón is located there is another waterfall known as the Pozo de Botarata. It is known by that name because a woman known as María la Botarate threw herself into it, because of a lack of love.


Don't miss out...


The viewpoint you will find following the path from which we deviated to go down to the Well of Airón. From this viewpoint you can observe the passage of the majestic Duero through this area and enjoy the magnificent surroundings.
