Access by car from Colmar: Take the western bypass around Colmar, then the D417 towards Munster, then the D10 towards Metzeral, Sondernach, then the D27 and D430 to Markstein, and park in the Markstein ski resort car park.
(S/E) Route and description modified in accordance with the notice dated 04/09/2023:
Follow the D430 towards Linthal, Guebwiller (eastwards) then, after the last chairlift, take the path on the left that goes around the Markstein refuge and follow the cross-country ski trails to the hairpin bend on the D430.
(1) Turn right onto a path (GR®532, yellow rectangular markings) leading to the abandoned Hofried farm, then to the D431 (ridge road).
(2) Just before reaching the D431, turn right onto theGR®5trail (marked with a red rectangle) heading north. Pass a trail on the right and continue parallel to the Route des Crêtes towards Markstein.
Return to the starting point.
(S/E) Turn left (north-west) onto the D27 towards Kruth and Thann, and continue for 300 metres from the Kruth and Thann sign.
(3) Turn left onto a path (red-white-red rectangular markings) and follow it to the Treh farmhouse inn.
(4) Continue along this path towards the Steinlebach farmhouse inn until you reach it. This path crosses the D27 and immediately joins a path that you take to the left, crossing a small metal bridge that serves as a cattle barrier. The path continues towards the D430, but 200 metres before reaching it, a path (marked with a red-white-red rectangle), which is poorly placed and can be easily overlooked, joins the D430 more quickly. Continue on the tarmac road opposite the path (marked with a red-white-red rectangle) towards the Steinlebach farmhouse inn.
(5) At the entrance to the Steinlebach farmhouse inn, turn right at an acute angle onto a path (marked with a red triangle) towards Markstein.
(6) Just after the water treatment plant, turn right onto a path leading to the Notre Dame Des Neiges chapel to arrive shortly afterwards at the starting point (S/E).
