Pedestrian and cycle bridge

Highlight • Bridge

This bridge is part of the circular route to the reservoir and many others that pass through this place. The environment is magnificent to do it both walking and cycling. Crossing from one side to the other becomes a peculiar experience.

Arantzazu Sanctuary

Highlight • Religious Site

The Arantzazu sanctuary is located between the green mountains, ravines and streams of Oñate. But its location is not the only thing that makes it special. Although the original building dates from the s. XV, the basilica was rebuilt in 1950 in a modern architectural style that has been recognized with several awards.

San Adrián Tunnel

Highlight • Cave

Curious formation that allows us to go from one side of the mountain to the other.
Be careful if it is wet or damp as the stones slip a lot.

Aizkorri Summit (1,523 m)

Highlight • Summit

An essential for those of us who live around here, without wind (which rarely happens around there) it must be a joy to sit quietly to have a sandwich. Well, actually, in the hermitage there is a small bench that looks towards the Guipuzcoan side where the wind does not usually blow. Too bad he's always busy.

Altar of the Virgin of Dorleta

Highlight • Religious Site

On August 8, 1960, the young Bilbao cyclists Luis and Ángel Serrano and the Vitorian José Luis Sáenz de Olazagoitia, arrived with their bicycles in Rome.

After a long journey from Vitoria, they were to be received in audience by Pope John XXIII. His saddlebags were loaded with illusion.

In that luggage they carried the request for the canonical declaration of the Virgin of Dorleta as the patron saint of cyclists. They say that the "good Pope", a fan of cycling and Bartali's tifossi, didn't take long to give them his blessing.

One of the highest points in the Basque Country, let yourself be enveloped by the fog and it will seem like a magical place.

This walk is beautiful but we did it in April and it was very wet and slippery. There was a part with lots of stones and mud and leaves where you sank half a meter. Not very steep until the sanctuary. There we had to zigzag very steeply up the rock. Better to walk up than down but that part is strenuous and not average.
