Colle di Sampeyre is a challenging and lesser-known mountain pass located in the Italian Alps, particularly in the Cottian Alps between the Varaita and Maira valleys. Known for its steep gradients and stunning alpine scenery, this pass is a favorite among avid cyclists looking for a tough climb away from the more crowded routes.

Colle di Sampeyre can be approached from several directions, with the most notable ascents being from Casteldelfino and Sampeyre. The climb from Casteldelfino is particularly brutal, with sections reaching gradients of over 14% over a distance of approximately 16 kilometers.
