The tour starts on the Simplon Pass. You hike via Hoppsche to the Gälmji (transition between the Staldhorn and the Tochuhorn). The view from the Gälmji towards the Aletsch region, the Brigerberg and Brig invites you to take a short break. At the fork, choose the left path, which is marked white-blue-white (alpine hike). This leads around the north side of the Tochuhorn to the Lengritz. It continues past the Undru Rossusee on the hiking trail that comes from the Nanzlicke. From there, the descent leads back to the Simplon Pass.
