(S) Depart from the car park south-west of Lake Lispach on the left-hand side of the D34C coming from La Bresse.
Follow the lake on your left, first crossing a wall serving as a dam, then continuing along a well-marked trail with occasional wooden walkways to keep your feet dry. At the end of the lake, leave the trail to the right and climb up a path towards the wide Ehlinger trail or the Collet de la Mine.
(1) At the crossroads, continue straight ahead on a path marked with a blue triangle, ignoring a path that descends slightly to the right. Follow the path on flat ground or slightly downhill through the forest. When you reach a paved section, face a building and continue down the road to the right.
(2) At a junction, leave the road climbing to the left and continue to the right to join the road along the lake. Cross the road carefully and continue straight ahead.
(3) Turn right onto a dirt track following the lake shore. You can visit the Saint-Florent chapel on the grassy hill. Continue along the lake shore and bear slightly left to find the road to the campsites, which branches off to the left, then the larger D67, which you cross.
(4) Cross the embankment opposite uphill to enter the forest. The route is marked with blue discs. Cross a road and head right into the forest. When you reach a forest road, follow it to the right until you reach the Boulard shelter.
(5) Continue south-east until you reach the major road D417. Cross opposite and take a path on the right downhill marked with a blue triangle. Continue downhill until you reach the D67 road.
(6) Follow the road to the left until the next junction, where you turn right. 50 metres further on, turn left at the edge of the campsite onto a path marked with a red cross. You will arrive at Lake Retournemer on your left.
(7) Follow the lake along its western shore. In a bend in the path to the left, follow a path marked with a blue disc to the right, which leads to the Col des Faignes at a crossroads.
(8) Turn right onto the D34c road and continue for 400 metres. At an elevation of 989 metres, you will come to some paths on the right. Pass an information sign on the right and follow the path marked with a green ring and a sign saying "Par sentier Dielaine Difficile" on the left, uphill. This path is steep at first, then becomes less steep but a little "technical".
(9) Do not take a path that climbs steeply to the left. Continue straight ahead through fairly wild, sparse forest, sometimes with large rocks and two passages equipped with safety cables. Descend to the left of the ski jump and exit the forest. You will reach a path coming from the left, which you follow straight ahead to reach the road and turn right to return to the starting point (E).
