The Sanctuary of the Virgin of Codés is located at the foot of the mountain range. It is a splendid 16th-century building built on the remains of a hermitage. The Baroque tower dates from the 18th century. The holy water fountain is next to the arcades, and there is also a guesthouse and gardens for relaxing and passing the time. The route climbs to the left of the building to a parking lot where signs and signs display the hiking trails. The path continues along the GR-1 long-distance trail, the Historical Trail, to Santa Cruz de Campezo, on the Álava side of the mountain range. The path is quite steep through a tunnel of oak trees, some of which are centuries old and stand out in a disturbing way against the dense forest.

Shelter in a magnificent location. It's not in bad condition, but it needs some improvements to make it an excellent shelter.

I advise reaching it from the south side, from Laguardia, in winter, and from the north side, from Lagrán, in the summer.

If you are interested in an "alpine" hike, you should definitely take the summit path from Puerto de Toro.

Characteristic summit of the Sierra de Toloña near Mount San Tirso. It is a steep peak that has the shape of a bishop's hat, from which the name comes.

Simply amazing postcards from the top of Joar at more than 1400 meters above sea level. To get here you can take alternative paths of greater or lesser degree of difficulty depending on your preference, in any case the route is very picturesque.
