Nice path through lush meadows. Only animals, no people.

There is usually confusion between El Esquilo and Fuente las Varas, well, El Esquilo is a pass that we find at this point and that takes its name from the neighborhood belonging to the municipality of Voto that we have just passed through if we have started the ascent in the Arás Valley. After crowning it, we only have to finish the ascent to the crossroads called Puerto de Fuente las Varas through much softer terrain, where we can enjoy the views offered by the Matienzo poljé and the peaks of Asón that can already be glimpsed. Peña Rocias, Colina and Porracolina.

Perhaps one of the most descriptive sites of which is the landscape of the Asón hills. Here, in addition, several paths converge that allow you to cover it almost completely, although when hiking, they can be very technical or even impassable for the bike.
