Col du Petit Saint-Bernard is a high mountain pass at an elevation of 2.188m (7,178ft) above the sea level, located in the Alps on the French-Italian border. The pass connects the Aosta valley in Italy with France and the Savoy region.
The road over the pass, depending on snow conditions, can be closed from October to June. The pass is located between Savoie, France, and Aosta Valley, Italy, to the south of the Mont Blanc Massif, exactly on the main alpine watershed. Either direction is driveable, although it is worth noting that the Italian side has the most severe hairpins – you may prefer to drive up the slope or down.
The French side of the mountain pass offers fantastic views over the valley. The road is well developed and offers some serpentines and tunnels. About 1 mile before you reach the pass summit, there are some abandoned buildings, just as you will find them on the pass summit.
