Col du Fréjus (or Passo del Frejus) is an international high mountain pass at an elevation of 2.542m (8,340ft) above the sea level, located in the Cottian Alps on the border between France and Italy. This international pass connects Bardonecchia in Italy to Modane in France. It's one of the highest mountain roads of the country.
The road over the pass is not paved but it was heavily used in the past. After 1974 most traffic was rerouted with the the construction of the Fréjus Road Tunnel.
This gravel trail has a slope that increases sharply with passages close to 12-13%. On the summit there are abandoned border barracks which had to provide security against an enemy invasion. The surface on this gravel road is often loose, especially along the sides of the road. It makes necessary to drive carefully.
The road to the Col was built in the 1890’s at the behest of the French Général-Baron Berge. Throughout the ride are old military ruins of barracks, forts, fortifications, etc, with the occasional information sign or historic plaque. There were minor skirmishes between Italian and French troops here in June 1940 (WW2). The area was controlled by the Italians soon after the French surrender to the Germans on June 22, 1940 — until the defeat of the Axis in 1945. Generally, the unpaved road is good quality. It’s occasionally very steep, occasionally slippery (new gravel stretches). The top stretch of the Italian side is only a very steep hiking trail.
