An incredible experience, we had a magical moment despite complicated weather with heavy rain and an icy wind. The road is quite scary to reach the drop point, going through professionals as was the case is therefore strongly advised, we saw a 4x4 which could not distribute on the return due to the rising waters when our guide knew perfectly how to maneuver. The short hike is wonderful, the stops and in particular the secret valley were breathtaking and finally the hot bath despite the impossibility of changing easily and the freezing cold was well worth all your trouble, go for it!
