In the Valley of Benasque there are many possible routes to choose from, but most are high up in the mountains, and you need to be experienced in order to attempt them. There are others like this in the Gorgas de Alba, which besides offering spectacular scenery and a nice walk along the river Ésera, are very easy to make, and we can cross it even with children. The trail, which is circular, has a length of 2.2 kilometers, a vertical drop of 130 meters, and estimated travel time of 1:15 hours. Along the way we will see many native trees and flowers, as the black pine, spruce and yew. The most characteristic species are indicated with a sign, so the road is very instructive.
