Between the regions of Lake Marcadau and Respomuso-Bachimaña rises the Great Facha, a perfect pyramid that rises almost 3,000 meters above sea level. It rests on three edges around other glacial cirques and numerous lakes. The proposed crossing avoids this beautiful pyramid. It is a mountain route that requires a good level of knowledge and training, but the trails are marked and the shelters duly signposted. The location of the refuges allows you to enjoy a wonderful three-day circuit that, without any additional effort, can include the ascent of the Great Facade, the kingdom of the granite pyramids.
