A beautiful valley with spectacular views, which can be accessed without difficulty (either from Ansó or from the Roncal valley), where you can breathe peace and tranquility and where you can enjoy a nice swim in the river on the hottest days of the year.

An ideal place to bathe in a high mountain river. The setting is idyllic and the water will surely refresh you! Don't hesitate to take a dip even if you have to take off your cycling shoes and jersey!

The Puerto de Laza is a small and beautiful hill that joins the valleys of Roncal (starting from Isaba) and Salazar (starting from Ochagavía) in the Navarrese Pyrenees. Both sides are very similar: a very easy start on a winding road, in perfect condition but without a hard shoulder, passing through small towns and going up the course of the respective rivers Anduña (Salazar valley) and Urbi (Roncal valley); a final stretch of 2 - 3 kms that is harder without being too much so, although there are some slopes above 10%. The Salazar valley side becomes harder when leaving behind the detour to the Larrau port. From here to the port there are 3 km with an average gradient of 7%. On the other hand, the Roncal valley side becomes harder when overcoming a bridge over the river that has been with us since we left Isaba behind. From here it is barely 2 km with an average gradient of 7%. From a landscape perspective, it is a port that I love because you can enjoy the exuberance of the vegetation of the Pyrenees, crossing narrow valleys and only with panoramic views when you reach the top, where there is a viewing point that is worth looking out at. A port that I always recommend for enjoying cycle tourism. I leave you the profile of both sides produced by the website www.cyclingcols.com --> http://www.cyclingcols.com/col/Laza

This montana center is also a bar, restaurant, and possible to repair the bike. The VAE will be able to recharge the battery in the beautiful restaurant/bar room. Super nice welcome.

The monastery of San Pedro de Siresa is a beautiful Romanesque-style monastery located in the town of Siresa (two kilometers from the town of Hecho). It is the oldest monastery in Aragon. There are guided tours of the monastery... and it is well worth it.

Great view at the summit of Agua Tuertas pista. There is an unguarded shelter before the Agua Tuertas section in which you can rest for the night, with tables, chairs and even a cheminée.
