Markstein - car park located at the junction of four roads (from Grand Ballon, Kruth, Col de la Schlucht and Guebwiller).
(S/E) Follow the path marked with a red rectangle (GR®5) which overlooks the road on the left-hand side and heads towards the Grand Ballon.
(1) Pass the Col du Hundsrucken and continue to the Col du Moorfeld.
(2) The path crosses the road and continues on the right (south-west at the start), descends then climbs, skirting the Storken on the right, until you reach the Ferme Auberge du Haag.
(3) Then take the path marked with red, white and red rectangles that runs along the right-hand side of the road to reach the summer toboggan run. See Practical Information.
(4) Then follow the road downhill to Markstein for about 200 metres. At the bend, take the Red-White-Red Rectangle marked trail heading north. This trail meets a path. At this junction, turn right and continue for about 100 metres.
(5) Turn left and follow the same markings. Pass the Ferme Auberge du Roedelen and the Ferme Auberge du Gustiberg,
(6) From there, turn left and follow the blue cross markings to reach Lac du Ballon.
(7) Turn right, take the stairs up and then, a little further on, follow the yellow triangle markings. At the fork with the yellow rectangle markings (GR®532), turn right and follow these markings. You will see the Riedisheim Ski Club refuge on your right
(8) Join the Route des Crêtes by heading to the right and follow it along theGR®5to the Moorfeld Pass, which you passed on the way there.
