Park at the Gazon du Faing car park, situated on the Route des Crêtes (D61).
(S/E) Turn your back on the road and follow the wide path for a few dozen metres.
(1) Keep to the right at the three-way junction and head for the ridge.
(2) Take the path on the left to reach the Taubenklangfelsen (1,299 m) or Rocher du Cri du Pigeon. This cluster of granite boulders sits on the main Vosges ridge, the famous ‘Terres des hautes limites’. Its name is said to derive from the sound produced by the wind in the rocks, reminiscent of the final cry of a pigeon fatally struck by a falcon – the peregrine falcon, which is very common in the area and finds this rock an ideal vantage point from which to spot its prey. Continue along the ridge to the Soultzeren Eck junction.
(3) Leave the path leading to the Gazon du Faing on your left and take the path almost directly opposite.
(4) Turn sharply right to begin the very steep descent leading to Lac du Forlet or Lac des Truites.
(5) Walk past the Forlet farmhouse inn, following the track; take the bend to the left, then leave the track onto a path on the right which rejoins it further on. Continue to the right until you reach the junction.
(6) Ignore the forest track on the right; walk for about twenty metres, then turn onto the path on the left which runs slightly above the track you have just left. You’ll reach a crossroads of paths.
(7) Head slightly diagonally to the left and reach the Spielmuss junction (elevation 1087).
(8) Continue along the path you have been following and walk a good hundred metres. Turn right onto the path that cuts across a bend, rejoin the path and continue straight ahead to reach Lac Noir.
(9) Cross the small car park, keeping the inn on your left. Follow the access road to the lake for about sixty metres, then turn left off it to follow the path that forms part of the GR®532. Begin a fairly steep climb to reach a forest track, which you should follow in the same direction. Once you are less than 100 metres from the departmental road, turn left to reach Lac Blanc directly.
(10) Cross the car park to reach the departmental road and walk carefully alongside it for about 200 metres. Then turn left onto the Sentier Keppel, which leads, after a short steep climb, to the Lac Blanc ski resort.
(11) Turn left to continue climbing
(12) At the fork, turn left to follow the ridge overlooking the lake and reach the source of Lac Blanc.
(13) Carry on to the left to skirt the Reisberg to the north, then turn sharply right to reach the Belmont Observatory.
(14) Carry on for about a hundred metres, then turn right to follow the path through the Tanet–Gazon du Faing Biological Reserve.
(15) Take the path on the right, pass to the south of the Gazon du Faing and head straight down to the car park where you started (S/E).
