Park in the car park of the Auberge de la Chaumière.
Marked with blue rings.
(S/E) Cross the D465 and follow the path to the left heading north. It follows the E5 and E2GR®5. It passes by "la Chaumière".
(1) Further on, turn left and climb up alongside the ski lift. The path enters the forest and turns right until it reaches a small road.
(2) Cross and continue opposite into the meadow along the D465. Pass the Auberge du Ballon car park and arrive at the Col du Ballon d'Alsace at an altitude of 1,174 metres. The route leaves the E2GR®5and continues following the E5.
(3). At the pass, cross the D465 and continue to the car park opposite. Here you will find toilets and a picnic area where you can enjoy your lunch in the shelter. Admire the monument in tribute to the bomb disposal experts.
Continue, paying close attention to the markings, until you reach a fork in the road.
(4) At the crossroads, turn right, then right again onto Chemin Colas, which descends steadily. There is a sign and markings to help you. You will arrive at the D465.
(5) Without taking it, climb to the right and cross the Jumenterie pastures, keeping to the right. Climb back up to the edge of the road and turn left.
(6) The trail joins the forest and crosses the Roches de Morteville. This trail is on a ledge. Take a short 10-metre detour to see the Rocher du Gouffre. Several other viewpoints offer extensive views of the surrounding ridges and the Vallée des Charbonniers. Please note that this trail is difficult. There are several passages with ropes to hold on to. Reach the Col de Ronde Tête or "Rundkopf" (elevation 1091).
(7) Continue on the left. Reach the Ronde Tête and its crossroads.
(8) Turn right, the trail descends fairly quickly to reach a crossroads.
(9) Stay on the right-hand path. The path winds its way between rocks like a roller coaster. It passes through scree. From there, the path climbs, sometimes in tight hairpin bends. At its junction with the path coming from the road, it levels out and remains flat until Trou de la Chaudière. Pass to the right of the Manheimer ski lift hut. The path, still facing you, emerges behind the Auberge de la Chaumière.
(1) Return to the car park by following the route in reverse (S/E).
