This 14 km long trail is the shortest trail on the list, but don't let the length of the trail fool you. For starters, the climbing on this trails is hard. When you leave Ainsa on a small tarmac road, the first climb on the backside of Bosque de Usana starts easy though a riverbed with little to no water, but after leaving that river it only goes up steeper and steeper, heading into the Sierra de Banaston up to the highest point of the trail Pumariello. Take a little time to regain your breath and prepare for the very technical first descent of this trail. Fornocal stage 7 of the EWS 2015. Short but super fun and the features just keep on coming.
After a steep pista climb up to de Corral de Raso, the beautiful second descent to Las Cambras starts. The descent starts pedaly and flowy but the more you go down the more technical it becomes. Don't forget too enjoy the stunning views over the lake. Be sure to tell me if can you make it through the big bumpy rockslab at the bottom of the descent :)
After passing Las Cambras you follow the road passing the church of Banaston, where a very short but steep descent waits that brings you at the bottom of a steep valley. Which you have to climb out to get to Usana. Enjoy this little village before you take on the final descent towards Ainsa, I live here! If you see me come and say Hi!
