From its summit, there are magnificent views of the Escudo mountain range and the Ebro Reservoir. The Magdalena Pass can also be accessed from the Escudo Pass, but the route includes a technical section and some stretches of dense vegetation.

La Matanela Pass, 1,005 m. Border between Burgos and Cantabria, Meseta and Pas. From Burgos, it's known as La Magdalena. I copied the altimetry from altimetrias.net, which can be trusted.

The height of La Estranguada is located at 687 m. above sea level and is located in a livestock area within the Pasiegos valleys. Quite a few cyclists usually climb it but it must be a high complex due to its important ramps and in our case an interesting starting point if we want to go to Los Pozos de Noja without walking many kilometers and withstanding a lot of unevenness, from here we head to Idillo and then to Los Pozos by a beautiful path or we can continue the track and shorten the path much more. What they do promise are some great views
