Departure from Lac de la Lauch (D430) between Guebwiller and Markstein. Small car park on the right-hand side of the road.
(S/E) Take the path marked with a yellow rectangle. After 125 m, turn right onto an unmarked path, heading east-northeast.
(1) After 800 m, this path joins a forest road, which you follow, still heading east-northeast.
(2) After 2.3 km, you will come to a path marked with a yellow cross. Take this path uphill to the Col de Lauchen.
(3) At the pass, follow theGR®532(marked with a yellow rectangle) towards the Klintzkopf protected area, which is off-limits from 15 December to 15 July to protect the peace and quiet of the capercaillie.
Please note that the red and white paint markings indicate a municipal boundary, which also marks the boundary of the state-owned forest, along the Klintzkopf ridge, which is off-limits.
Outside this period, you must go around Klintzkopf to the south via the forest path (also marked with yellow rectangles) between the Lauchen and Oberlauchen passes, following a contour line to the west.
(4) From the summit, descend towards the Oberlauchen Pass and continue on theGR®532.
(5) At the edge of the forest, take the ridge path over the stubble fields. Cross the Lauchenkopf and Nonselkopf.
(6) Further on, turn left (entering the forest) onto a path that joins the D27 road.
(7) Follow the road to the left for 125 metres and turn right onto the path that leads to the Uff Rain farmhouse inn.
(8) Just before the farmhouse inn, take the red-white-red marked path that joins the ridge road (D27) at an altitude of 1248 metres, above the Salzbach farmhouse inn.
(9) Source of the Fecht river on the left of the path. Cross the road and continue along the blue-marked path to the Oberlauchen Pass.
(10) Take the yellow rectangle marked path on the right, which descends rapidly to Lac de la Lauch (S/E).
