Ascent of San Lorenzo, the spectacular summit of Cuculla

The natural space of the Sierra de la Demanda extends between the neighbouring provinces of La Rioja and Burgos. In the part that corresponds to the Riojan municipalities of Ezcaray and Villavelayo is the Ascent to San Lorenzo by Bogolrrucia. ​

Ascent to San Lorenzo by Bogolrrucia. ​

This mountainous space of easy access, is forming by a chain of high and rounded mountains that separate the valley of the High Oja and it of the High Najerilla. Surrounding the San Lorenzo peak, the highest in La Demanda and the second highest in the Iberian System to which it belongs, runs this route that will take us to contemplate the different places that these mountains separate, along with the magnificent views that the summit of San Lorenzo offers us, thanks to the relative ease that these summits offer in summer.

Ascent to San Lorenzo by Bogolrrucia

This simple route of 4.5 km in total allows non-mountainers to enjoy the ascent to a summit of more than 2000m, partly thanks to starting at a good altitude and saving only a slope of 311m in 2.25 km. From the pass of San Lorenzo where it begins, we contemplate surrounded by rounded peaks, the valley of Oja and high Najerilla. The well-defined trail runs along the hillside dominating the upper Oja valley and escorted by the peaks near the Cruz de la Demanda. The Bogolrrucia pass is a splendid balcony from where you can admire the Pancrudos and sense the path that climbs up the valley from San Millán de la Cogolla.

Summit of San Lorenzo

At the comfortable summit of San Lorenzo the altar to the Virgin of Valvanera awaits us, where every 10th of August a mass is celebrated in honour of the patron saint of Ezcaray, San Lorenzo, as well as a figure of esté. On clear days and with good visibility, the panoramic view is spectacular, with part of the Pyrenees, the Moncayo and the Muela del Urbión among others, also dominating the Ebro valley as it passes through the Rioja Alta.

The Trick

If we want to extend our walk we can descend by the east shoulder of the San Lorenzo until arriving at the beginning of the ascent to the Cabeza Parda, where it begins a path that descends until the encounter of the track that raises from San Millán de la Cogolla, continuing by her, surrounding the San Lorenzo, to arrive at the parking of the hill.

How to get to Valdezcaray

At the car park of the San Lorenzo pass 24 km from Ezcaray, we arrive following the LR-416 that goes up to the ski slopes of Valdezcaray and from there continuing along the path, which still preserves the remains of the asphalt that covered it, until the pass. In the road LR-415 that joins Ezcaray with Posadas this road of access to the station begins. Ezcaray has a daily bus service that connects it with Stº Domingo de la Calzada and Logroño. Ezcaray can be reached by following the LR-111 from Stº Domingo de la Calzada or by this same road but from the neighbouring town of Burgos, Pradoluengo. Once in Ezcaray following this road we find, near the church, the crossroads that leads us to Posadas and the ski resort of Valdezcaray, continuing then by this detour we will cross the river Oja and we will turn to the right to continue by the road LR-415 where to few Km is the detour where the road LR-416 of ascent to Valdezcaray begins, this road in snow season ends in the parking lot of the season but in summer it is possible to continue more with the vehicle, the road has ended up becoming a path by the action of snow and ice. After leaving on our left a couple of paths that lead to the ski slopes, the route goes up along the hillside of San Lorenzo until it reaches the crossroads where it joins the paths that go up from San Millán, Mansilla and La Cruz de la Demanda, where the car park of the San Lorenzo hill is located.

Pet area, mountain with my dog

The route is mainly made up of trails made up of small slabs.

There are no water points along the whole route, especially in summer.

In winter it is only usual to find some more pets, and from afar with the animals that live in the area, roe deer and wild boar, in summer it is cattle territory, being normal to find sheep and goats around the summits taking advantage of the fresh stems of the bushes and cows in the pastures of the hill between the Alto de Bogolrrucia and the San Lorenzo.

Description of the ascent to San Lorenzo by Bogolrrucia

From the car park to the pass of Bogolrrucia

We begin this route in the Parking of the pass of the San Lorenzo (0h 00min), from it the trail that ascends to the San Lorenzo starts. The path that we go up to here, forks in two wrapping one of them to our objective, the San Lorenzo, to continue its course towards San Millán de la Cogolla.​

Start of the trail next to the crossroads and car park

Just in the curve that makes this path begins the trail, which runs up the hard initial steep in a straight line by the shoulder of the mountain.

The trail runs along the slope of the mountain

Before reaching the summit of Bogolrrucia, the trail turns clearly to the left, leaving on our right the trail, less marked, that leads to this summit.

View of the route and the car park

We continued the itinerary, now much softer, bordering the skirt of Bogolrrucia by a well-defined trail that little by little is gaining height by the hillside of the mountain, offering us the opportunity to contemplate the magnificent landscape that forms the Oja valley.

From the pass of Bogolrrucia to the summit of San Lorenzo

The route departs from the cobblestone hillside of the mountain to the wide Bogolrrucia Pass (0h 25min), crossing it from side to side in search of the next challenge of the day.

Some blue marks indicate the beginning of the trail through the shoulder of San Lorenzo

This practically flat section allows us to finish recovering to face the final part of the ascent. Once we cross this hill, the path climbs over the shoulder of the San Lorenzo.

Climbing trail San Lorenzo

The first zone is the hardest and the one that in worse state we are going to find, saves a good unevenness by a somewhat decomposed land.

The hardest ramps of the entire route

With the typical zigzagging that allows us to gain height step by step, the route ascends, overcoming the greatest unevenness of the entire route, by the skirt of San Lorenzo.

Reaching the summit

In the vicinity of the summit the trail and the unevenness are not so evident, moment that indicates us the proximity of our objective, we must be attentive and take references that help us to find the way back to our return.

Return from San Lorenzo

The last meters of the route through the wide and bare summit shows us the milestone of the San Lorenzo summit (1h 15min) and in the background the altar to the Virgin of Valvanera.

Descent along the same route following the blue marks

We will return following our steps, although finding the path with blue marks that brought us to the top can be somewhat expensive the good visibility of the rounded mountain and the comfortable slope of the shoulder where we climb allows the more accustomed, go without following any path in the direction of the Pass of Bogolrrucia (1h 30min) and there find the trail just before it reaches him.

Spectacular landscape on the way back

From here we can continue along the path that cuts the skirt of the mountain to our starting point or continue straight through the cordal that ascends to the Alto de Bogolrrucia, a simple route that allows us to ascend another peak of more than 2000m.

Bogolrrucia Pass

If we follow this option and once we have conquered the summit we must continue along the mountain range until we reach the summit we ignored at the beginning of the route, to descend straight from it joining us with the original path and arrive at the Parking of the San Lorenzo Pass (1h 50min).​

Technical data sheet of the route

ico-distancia-totalDistance. 4,5 Km

A relatively short route as long as we can park in the indicated car park.

ico-tiempo-totalTime. 1:50h

From the Collado car park, if we also include the ascent of Alto de Bogolrrucia in the descent, we will have to add approximately 30 more minutes.

ico-calendarioTime of year

Without snow or ice and wit:good weather is an accessible route, advisable and allows the less accustomed to enjoy the experience of climbing mountains over 2000m. The summer, spring or early autumn wit:more days of good visibility allows us to entertain ourselves contemplating the wide panorama that the summit of San Lorenzo offers us.

ico-materialRequired equipment

Clothes and sports or mountain footwear according to the time of the year and the weather, the canteen wit:water if we make the route in summer and the backpack wit:the usual. Consult our list of material and equipment for hiking. Read more.

ico-dificultadDifficulty. Medium


This route is physically undemanding, bot:because of its distance and the slope to be overcome, althoug:we must not forget that we are above 2000m, we will find the two areas wit:the greatest slope at the beginning and at the end of the route, the intermediate part of the route being a comfortable approac:to face the final climb.

Severity of the environment

No technical difficulty, as long as we don't find snow or ice. The ascent to the top of the San Lorenzo is made by a well-defined trail that borders the hillside of the mountain, a real stony field in some of its sections. In the initial part of the ascent, after the intermediate pass, there is the area wit:the most decomposed trail and the steepest slope.


Without any signposting, in summer the paths and trails are perfectly defined and wit:good visibility we have as reference the top of San Lorenzo for the climb, for the descent from its top the pat:is not entirely clear, so to locate it just direct our first steps to the southwest, taking as a visual reference the peak Salineros where we come from. Fogs and rapid weather changes are common in the area, making it relatively easy to become disoriented.
