A descent that starts in an area that is completely free of plant life and goes into the valley, where the forest becomes gradually thicker with obstacles that will need to be avoided. As the route descends, so the difficulty increases. It finishes at an altitude of 1,985 m, at the Comellar Llarg path. This is where you will put on your climbing skins to start the return towards the Forn de Canillo or the Riba Escorxada Plain.
A wide, unspoiled, steep slope free from obstacles meaning you can ski in complete safety with two possible alternative return routes (foot of the TSF4 Els Clots and Rossinyol slope).
A 20-minute climb with climbing skins that starts at the Rossinyol slope. It goes through stretches of forest and clearings without any significant climb until reaching an altitude of 2,315 m. The descent is through the forest, where there are passages between rocks and a brook that take you to Forn Lake, at an altitude of 1,965 m, 5 minutes from the TSD4 Portella.
