The Walk of the Oca, a family excursion

Under the protection of the Montes Obarenes - San Zadornil Natural Park, at the very gates of the rugged La Horadada gorge, the beautiful town of Oña and the Walk of the Oca await us. As a natural border between the Castilian plateau and the Cantabrian area, Oña has been for years the natural pass used to unite both territories.

Walk of the Oca

The Walk of the Oca with its 4 Km crosses the imposing gorge of the Horadada, following from the same heart of Oña, the conditioned footpath that furrows it. The Monastery of San Salvador and the historic centre of the town rival in beauty with the natural environment that surrounds them. Verticals cut rocky of more than 200 m imprison the flow of the river Oca as it passes through this narrow gorge. The path advances in good measure parallel to the national one, encountering along its route several bridges by which to cross from one side to the other of the riverbed. The tranquillity of the recreation area of So Castillos invites us to make a stop on the way to enjoy the place we are visiting.

Oca River Walk of the Oca

The old railroad track that crossed this pass also has to accompany us in part of the itinerary allowing us to contemplate the vestiges of its past splendor. Later on we will reach the end of the Walk of the Oca, marked by the national one that crosses in our way. Here, before turning around to return to Oña, we will be tempted to continue a few more metres following the signposted route of the GR 1006 and SLC-BU 107 footpaths with which we shared our wanderings. These cross under the national one and, on the other side, surprise us with the last of the bridges crossing the river, undoubtedly the most spectacular of all and worth approaching before returning to Oña, and putting an end to this beautiful excursion.

The Legend

Legend has it that in one of the tapestries that adorn the walls of the Monastery of San Salvador de Oña you can contemplate the legendary history that is part of the origins of Castile. And this canvas tells the story of how an ancient king, lord of these lands infatuated by a magnificent horse and a bold goshawk owned by Count Fernan Gonzalez agreed with him his transfer for a few days in exchange for a large sum of money. But the infatuated king as he was with both animals wanted to keep them in his power longer, not realizing that the passage of time increased the debt he contracted with the count. This debt became so important that the king had no choice but to cede the County of Castile to the Count with its full independence.

How to get to Oña

As far as Oña we arrive following the N-232, national road that crosses the locality. Oña is also reached by local roads that connect it with neighbouring villages. Once there, along the national road as it passes through Oña, we will find parking areas where we can park our vehicle. Although the closest to the beginning of the route is located on the other side of the river and the outskirts of Oña Trespaderne direction, next to the old buildings of the train station.

​Pet area, hiking with my dog

Pleasant walk in which our friend should not have any problem, but we can not get distracted to avoid unnecessary scares.

The water is practically guaranteed to pass through recreation areas where we will find fountains.

Except for the pets with which we can coincide it is not habitual that we run into other animals.

Technical details of the Walk of the Oca

ico-distancia-totalDistance. 4Km

Our starting point marks the distance to be covered.

ico-tiempo-totalTime. 1:00h

In reality, this is the time we will need if we venture a few metres further on to the imposing bridge that crosses the Oca River at the entrance to the gorge.

ico-calendarioTime of year

Throughout the year the Walk of the Oca is a good colophon to our visit to the locality of Oña. The imposing landscape that surrounds it and the pleasant of the route invite us to make it without haste, with the exception of four counted days in which the bad weather discourages it.

ico-materialRequired equipment

The state of the route and the short distance to travel allow us to face it as the walk it is, but always taking into account the weather conditions. Consult our list of material and equipment for hiking. Read more.

ico-dificultadDifficulty. Low


With hardly any distance and an almost negligible gradient, except for a couple of short ramps, this excursion should not be a problem for us.

Severity of the environment

The walk is well conditioned and protected from traffic in areas where we advance next to the national so as long as we do not leave the marked itinerary and apply common sense should not find complications, as long as the terrain conditions are normal good weather. However, we must not forget that we are surrounded by the enormous cliffs of the gorge so we are not exempt from possible rock falls.


Embedded by the conditioning of its layout the greatest complications will find them to find their beginning, not having clear in advance where we should go. Likewise, at the end of the Walk of the Oca the doubts will be able to assault us since the marks of the footpaths with which it coincides invite us to continue without any sign warns us of the end of our route.
