5h -11km approximately

From the Oberalppass station, start with a descent by traversing the high mountain pasture called Plauncas Cuflegl  at the foot of steep and avalanchous slopes to the SE then S. Be careful in heavy snow conditions, this high mountain pasture is a genuine source of large sluffs. Around 1900m, to the E of point 1831 (Surpalits), put your skins on. Heading S, you first traverse a depression and its stream. Continue primarily to the S and via gentle slopes go up a broad valley while passing through the Tgatlems and Plidutscha high mountain pastures to point 2174. Be careful in this valley as well, sluffs come down from the slopes to the W of Plidutscha.

From point 2174, head diagonally towards the W and take a steeper, narrower and more effective slope which leads to Lai da Tuma (2345m). Traverse or go around the lake depending on its condition (if in doubt go around it!) and continue W passing by point 2399. Around 2500m, the slopes level out. Go around a rock band on the left to the foot of Parlet around 2600m. Leave Älpetlilücke on the left, head to the NW and, via gentler slopes, you reach the summit (2836m). Splendid view of the valley of Surselva, the Oberalpstock range, the Uranaises Alps and, towards the W, the eastern summits of the Berner Oberland.

Descent by the same route, which means ending by putting your skins back on to return to the Oberalppass station.

At the end of the season, when Oberalppass is open to cars, it is possible to reach point 1831. You start the tour slightly to the W of this point and avoid putting on your skins when returning as mentioned above for the winter route.

It is possible to carry out the traverse towards Andermatt (HD: -1400m) by descending the W and then SW slopes of Rossbodenstock.

Possibility of reaching Pazolastock (2740m) via the crest which passes via Martschallücke (2684m). Numerous possible sequences in the surroundings. Via Lai da Tuma, Badus (2928m) and Martshallücke (2684m). Slightly more to the E, you can reach the Piz Cavradis (2614m) via Camona da Maighels. You can also climb Pazolastock (2740m) descending via Lai da Tuma and point 2174 then going up its E slopes (Nurschalas Grondas). You can then descend directly towards the station of Oberalppass by the NE slopes.
