            • Saturday Hike
               On Saturday, 27th 2022, a group of 9 participants, among them 4 di↵erent nationalities, started by car from Benasque at 7am to go for a one-day hiking tour which led us to the famous cascades (Aigualllut) and to a wonderful vast plane above from where we got still a bit higher in the direction of the Aneto. We settled down for a while, had a picnic together, took a lot of photos of some scenery around this beautiful trail and then returned to Benasque enriched by so many wonderful views we had profited of: here you may find or rediscover some of them in this album.
