Greenway of the Oja, the history of the old train Bobadilla

The Greenway of the Oja, section 1 Casalarreina-Stº Domingo de la Calzada takes us through the great alluvial plain of the Oja valley, in the foothills of the Ebro valley, between the towns of Casalarreina and Santo Domingo de la Calzada in La Rioja.

This first stage of the greenway allows us to enjoy a varied landscape of poplars and farmland, as well as the great cultural and historical heritage of the towns through which the old railway route passes. With 12,7 Km, it not only crosses the immense plain that form the valley of the Oja in its confluence with it of the Ebro, but also part of the nourished history that this land has.

From Casalarreina, with its spectacular historical and cultural complex, with imposing palaces marked by the 16th century Monastery of Nuestra Señora de la Piedad, recalling the bustling activity that gave life for 47 years to the Bobadilla train, the landscapes that we will cross, observed by the Sierra of the Toloño and the Obaranes Mounts, show us the different crops that have a place in La Rioja, from the vine, passing by the wheat and the barley and without forgetting the potato, the cultivation fields will accompany us during the whole route.

At the end of the route, the unmistakable needle of the Tower of the cathedral of Santo Domingo de la Calzada from the 13th century greets us on the horizon, as if they were pilgrims, until we reach Santo Domingo de la Calzada, where this part of the Greenway of the Oja ends. ​

How to get to Casalarreina

To get to Casalarreina we can do it by the N-126 from the nearby town of Haro, on this same road is the toll access to the AP-68 motorway. We can also arrive by the N-232 between Logroño and Pancorbo, in addition the LR-111 joins it with Santo Domingo de la Calzada and Ezcaray, the LR-311 joins it with Zarratón and the LR-310 with Cihuri. There are several daily bus lines with stop in Casalarreina that make the routes to Bilbao, Vitoria, Logroño, Santander or Burgos. Once there in the exit towards Logroño for the old national, now Avda. de la Paz, we will find a wide parking and a few meters later the detour of the road towards Zarratón, is in this one and before leaving definitively of the locality, where it begins the way that takes us to the official point of beginning of the greenway.

Pet area, hiking with my dog

It is a beautiful route that is almost completely paved, except for the section close to the road, where we are forced to cross the road several times.

We will only find water points in the towns, forcing us to be attentive to the water we carry, especially on hot days, as there are virtually no shaded areas.

The route passes near Santo Domingo de la Calzada between some recreation estates where we can find some mascot, usually within the enclosure, also in the vicinity of urban centers we find similar cases.


Description of the Greenway of the Oja. Section 1 Casalarreina-Stº Domingo de la Calzada

We began the route in Casalarreina (0h 00min), travelling part of the road of Zarratón until just at the exit of the locality, next to some agricultural pavilions, we turned to our right to continue by the path that crosses between estates of fruit trees.

Detour on the road to Zarratón

With the well of the water in our horizon, this path gives us the first samples of what will be the straight run of the green way. Shortly after passing through it we find, next to the water well, the road that connects Haro with Santo Domingo and on the other side of it the official starting point of the Greenway of the Oja.

Crossroads with the road and official start of the greenway

Crossing the road we begin a long stretch asphalted and shared with vehicles, in this part of the route they are mixed between the different types of cultivations that characterize this Riojan land.

Section shared with vehicles

Leaving to the left and right all the paths that cross with us, we head towards a poplar grove that will give us part of the little shadow that the itinerary has. After leaving this wooded area behind, the road starts a gentle ascent to reach another crossroads where a dirt track begins, parallel to the main path and which avoids the traffic we might encounter.

Walkway between the road and the path

Little by little we get closer to the edge of the road that we crossed before, until when arriving at its height, the new layout of this one, cuts the old run of the railroad, that without changing its rectilinear course, passed by the outskirts of Castañares de Rioja.

Crossroads near the roundabout of Castañares de Rioja

This new route continues between the road and the path that gives access to the different farms in the area, to reach the vicinity of a roundabout. At this point and with the roundabout on our right, we are forced to cross the road that stands in our way to continue along the path that continues encased on the other side. This section next to the road continues until we reach the original layout of the road, at which point, turning sharply to the left, we will leave behind the road company to recover the course that, without detours, will take us to our objective.

The greenway intersects with countless roads

This part of the route recovers its good firm again, it could be said that this asphalted one, crosses extensive cereal estates marked with some solitary tree and is crossed with a good number of paths that we will leave to left and right.

last intersection of a road

The path meets again with a couple of local roads that we will have to cross and continues straight on, observed by the imposing silhouette of San Lorenzo and the mountains that accompany it. Shortly after passing close to a solar plant we arrive, between some recreational farms, we arrive at the meeting of another road that forces us to cross it to continue our journey.

A-12 Underground Passage

The final part of this section crosses below the national to cover the short distance separating it from the next town it passes through, entering it after passing by a pavilion.

Entrance to Santo Domingo de la Calzada

The greenway reaches the outskirts of Santo Domingo de la Calzada (3h 15min) next to the Red Cross post where this stage ends, at the entrance of the old national road that from Logroño passed through here.
