Preliminary remarks: the name Martschalstock does not appear on topographical maps. It is spot elevation 2743 to the N of Martschallücke (2684m) and to the NW of Fil Tuma.

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 state (if in doubt, go around!) and continue towards the NW in an obvious scoop (Alp Tuma) which leads to Martschallücke. Do not go to this pass. At around elevation 2500m, pull towards the N to find the foot of Fil Tuma and skirt this rocky dorsal to the NE to reach the SE pass (2620m) of Martschalstock. Go back up the ridge to the NW until the summit (2743m). You can also be satisfied with Martschallücke (2684m).

Descent by the same route or directly under the summit (slightly steeper) without passing via the SE pass again. You need to put your skins back on to go back to the station of Oberalppass. It is possible to carry out the traverse towards Andermatt (HD: -1300m) while descending via the slopes of Pazolastock or Rossbodenstock.

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 reach Pazolastock (2740m) and Rossbodenstock (2836m) via the ridge which connects these two summits and which passes through Martschalstock and the Martschallücke. Numerous possible sequences in the surroundings. via Lai da Tuma, Badus (2928m) and Rossbodenstock (2,836m). Slightly more to the E, you can reach the Piz Cavradis (2614m) via Camona da Maighels. You can also climb Pazolastock (2740m) via its E slopes (Nurschalas Grondas) and descend towards the station of Oberalppass via its NE slopes.
