Parking is available in the village on Chemin du Herrenberg (via Rue Raymond Poincarré) or on the square in front of the Hôtel Valneige, from where Rue Erbersch begins.
(S/E) From the car park, after 60 m, turn left onto a path running alongside the Fecht. Cross over the Kolbenfecht and join Rue Erbersch; follow it up to number 48, at the entrance to Chemin du Kastelberg.
(1) Take the Blue Triangle trail towards Kastelberg. The trail climbs steeply above Mittlach. It’s a fairly steep ascent through the forest, with a bit of cool relief provided by the stream, which is never far from the trail.
(2) When you reach the forest road, turn left. Leave the forest road shortly after the left-hand bend, taking thefirst path on the right, which climbs very steeply. A steep climb through blueberry bushes.
(3) At the junction with a Blue Triangle-marked path heading uphill to the right, turn left then immediately right onto the Blue Cross path, towards Kerbholz; finally, a bit of flat ground.
(4) Walk round the mountain hut, ignoring the paths branching off to the right, and take theGR®531path, signposted with a Blue Rectangle, towards Kastelberg.
(5) At the Kastelberg farmhouse inn, follow the signs for the ‘Sentier des Névés’ via the connecting path leading north-north-east from the car park.
(6) At the junction, take the ‘Sentier des Névés’ marked with a Yellow Cross towards the Col du Wormspel (and the Hohneck). A ridge path with views of the Hohneck and the Wormspel cirque.
(7) Wormspel Pass, at the foot of the Hohneck; you can make a round trip to the summit to enjoy the view or have a blueberry tart.
From the pass, leave the Yellow Cross markings and take the Blue Triangle path, which descends to the right towards Lake Schiessrothried and the Wormsa. Steep descent; chamois are frequently sighted in the area.
(8) At Lake Schiessrothried, follow theGR®5path to the right, marked with a Red Rectangle, towards Wormsa (just before the dam).
(9) When you reach Fischboedle Lake, continue on theGR®5to the left, ignoring the path on the right marked with a Blue Cross. You will very soon reach a Fork in the road.
(10) Leave the Fischboedle Path (Red Saltire) on your left and continue to the right on the Wormsa path (GR®5 ). It passes over numerous small wooden bridges and a few scree slopes.
(11) At the bottom of the valley, keep following theGR®5(Red Rectangle) to the right to head back towards Mittlach.
(12) At the next junction, turn right again onto the road to return to the centre of Mittlach (S/E).
