The ascent to Mount Beriain or also called San Donato is a desire that seizes us as soon as we see its silhouette from the valley. In this physically hard route we will ascend to the Hermitage located at the top through an acceptable path that will lead us first to the place called Dukenasa where the outward and return branch that leads to the hermitage and viewpoint.
This branch is about 13 km long and is worth the trip for the spectacular views alone. Then, we continue bordering the mountain range until we reach the Lizarraga tunnel, where the Borda and Benta are located and where we can recharge our batteries. At this point it should be clarified that the only technical area through which this route is cataloged as difficult is just after the passage of the road so if you do not dominate the bike in technical areas, we recommend that you go down the campsite directly on the road.
On the other hand, if you continue with the route, we continue along the edge of the mountain range and after a brief incursion to the Ermita de San Adrián and its viewpoint, we begin the descent along a path with a more technical first part and an easier final area. If you like technical descents, you’re sure to enjoy it.
