Great viewpoint of the Agadon Valley, a mandatory stop on the way up to Peña de Francia or the descent, to take more photos and read interesting facts on the information panel.

The climb up this narrow valley is a delight, especially on days when there is not much traffic. The views, the sounds of nature, the vegetation, the aromas of rockroses and other wild flowers allow us to almost forget that we are going uphill for a good part of the journey :-D

Nice 12 km ascent from the Puentes del Alagón to San Miguel de Valero. Almost 500 m of ascent, so it requires form. More than half of the climb passes next to the banks of the Río de las Quilamas.
