Donon Summit Trail

The Donon summit trail is a loop of about 6 km in the Vosges mountains, starting at the Col du Donon near Grandfontaine in the Bas-Rhin, on the border with Meurthe-et-Moselle in the Grand Est region of France. The Donon rises to about 1,009 m and is a well-known landmark of the Vosges, topped by a replica of a Gallo-Roman temple and surrounded by remains linked to a Celtic and Gallo-Roman sanctuary. The walk involves roughly 250 m of climb, which places it at the easy end of the scale, though the grade is steady. Access from Strasbourg is by car in about 1 hour 10 minutes via Molsheim and Schirmeck. Regional bus options through Schirmeck exist, and visitors should check Fluo Grand Est for current schedules before relying on them. Parking is available at the col. The path alternates between forest tracks, rocky footpaths and sandstone steps near the top. Large sections are shaded by spruce and beech, while the summit area is open and exposed to wind and weather changes. Key landmarks include the temple replica, carved sandstone stelae and viewpoints that look across the surrounding forested ridges toward the plains of Alsace and Lorraine. Waymarks of the Club Vosgien guide walkers along the circuit. A sensible turn-around point is the summit itself, after which the same route can be followed back to shorten the outing. No reliable water source is available on the trail, so visitors normally carry water for the full 2 to 3 hours. Facilities at the col vary by season, and there is limited shelter on the upper part of the walk apart from the temple structure and the trees. In winter the trail may be covered in snow or ice, and fog can reduce visibility sharply. The area is popular with local walkers and school groups, particularly on weekends in good weather, while weekdays offer a quieter experience.
