(S/E) From the Lac de Kruth car park (547m), cross the dam, walk along the lake and then climb up to the left and immediately to the right into the forest.
(1) The path goes around the Vörder Bockloch (903m), crossing several streams and waterfalls, and offers glimpses of the summit of the Grand Ventron in places.
(2) It then joins a track which you follow uphill towards the Col du Bockloch.
(3) Before reaching the pass, take a small path on the left that leads to theGR®531and the summit (1204m).
(4) Cross the Chaume du Grand Ventron and continue along the ridge to reach the Petit Ventron (1155m), the Tête du Chat Sauvage (1153m), the Chaume des Vintergés (1086m) and finally the Haut de Felsach (1161m).
(5) Cross the Felsach meadows to reach the path that continues on from the track leading to the farmhouse inn.
(6) Descend towards the Frentzbergel chalet and turn left once you reach the track. Follow it for 500m and then take a small path that descends to the right.
(7) A few hundred metres further on, this path begins a hairpin bend, so leave it and continue straight ahead on a path that descends steeply.
This leads to a track below, which you take on the left and which brings you back to the starting point of the route after a few kilometres (S/E).
. For my part, I clocked up 19 km.
