The road to Frejus Pass in the Cottian Alps was built in the 1890’s

# Col du Fréjus: Alpine Adventure on the Franco-Italian Border

Ready for an epic mountain experience? Col du Fréjus sits pretty at 2,546 meters (8,353 feet) where France and Italy shake hands in the stunning Cottian Alps. Also known as Passo del Frejus, this pass connects Italy's Piedmont region with France's Savoie department—and trust us, the views are absolutely worth the drive.

At the summit, you'll find a charming little lake (Petit lac du Frejus) and a cross marking the border. Plus, there's a fascinating layer of history here. The original road was carved out in the 1890s by French Général-Baron Berge, and what really sets this pass apart is the collection of military ruins scattered throughout the route. From abandoned border barracks to old forts and fortifications, you're basically driving through a living history book. There were even minor skirmishes between Italian and French troops here in June 1940, and the area changed hands several times during WWII before finally being liberated in 1945.

Now, here's the catch: the French side is completely unpaved and requires serious 4x4 capability. The road quality isn't terrible, though it can get slippery. Fair warning—private vehicles are currently restricted here. The Italian side? That's hiking-only with a seriously steep trail.

If you do make it up the French route starting from Le Seuil, you're looking at an intense 8.4-kilometer climb gaining 873 meters with pitches hitting 30% gradient. Average grade sits around 10.39%—brutal but doable for serious adventurers.

It's worth noting that since 1980, most traffic takes the 13-kilometer Fréjus Road Tunnel instead, which means the pass stays wonderfully remote and atmospheric.
