Fort Redoute Ruinée

The historic Alpine fortress Redoute Ruinée, also known as La Redoute, is located on the Crête du Roc Noir ridge, southeast of the southern ramp of the Col du Petit-Saint-Bernard on the French side. Access to the fort is possible from La Rosière. The access road branches off from the N90 about 300 meters east of the gas station at the edge of town and first leads to Les Eucherts. From there, it passes through the local golf course before the actual trail to the fort begins, stretching approximately 7.5 kilometers. This route is partially rough gravel and steep, with inclines of up to 30%.
The path winds up to the Roc Noir with numerous switchbacks, reaching the level of the ridge. Along the way, several ski slopes are crossed, so care is needed to avoid taking a wrong turn. The final 2.5 kilometers to the fort run as a ridge road, offering stunning views into the valleys below.

Unfortunately, the fortress itself is not open for visitors.

The approximately 1.5-kilometer-long, steep northern descent leading to the summit of the Col du Petit-Saint-Bernard is technically drivable but is currently officially closed.
