We leave Sallent de Gállego to go towards the municipal swimming pools, from there on the right, we take a path that will take us to the height of La Sarra and then continue with the GR-11 until we reach the height of the Caseta de Ibonciecho and from there turn right in the direction of the Puyarcol pass.
Once we have reached the top of the pass, we go down to return to the Caseta de Ibonciecho, where we turn right to follow the track and take the path of the pipe to reach La Sarra. Once we have finished, we turn left to go along the track to the La Sarra bridge. Cross the bridge and head towards Refugio de Respomuso. After one kilometre, on the plain of Tornalizas, we leave this path to take another one towards the Ministirio valley.
