From the shelter we quickly reach Port de Vallcivera, leaving behind Estany de l'Illa. At this pass, on Catalan-Andorran border, we leave the GR and turn off to the right, following the track along a section with no defined path, but we will clearly see a small hill which will allow us to reach Tosseta de Vallcivera (2848m). We descend Coll de la Portelleta to quickly ascend to the highest point of the route, la Tossa Plana de Lles (2916m).

We reach Pic de Setut along a wide crest, where we begin the trickiest part of the route. From the small hill to the side of the peak we begin our descent along a scree, to later go around it to reach Port de Setut. To reach it we will find two paths where we will need the help of our hands, and once through, we will ascend Collada Fonda and Tossal Bovinar, reaching them from the right-hand side of the scree. From this point we gently go up to Pic dels Estanyons (2834m), the highest peak of the route, and from where, along an open and very evident grassland, we drop down to Refugi dels Estanys de la Pera, a shelter that is manned during the summer months and at weekends.

At this shelter we retake the GR, and heading upwards it takes us to Port de Perafita, where we once again enter Andorra through Vall de Perafita. Without leaving the GR, it will bring us to Pot d'Entremesaigües in Vall de Madriu after leaving Refugi de Perafita behind.

From the bridge, all that remains is the initial section of the route, which quickly and without difficulty takes us back to the starting point.
