Route: D1090 & SS26 Bourg St. Courmayeur (36 miles)
The Petit (or Piccolo) St. Bernard links Bourg St. Maurice in France with Pre St. Didier in Italy, near Courmayeur where the Mont Blanc tunnel takes you through to Chamonix in France. At the top, where the WWII fortifications can still be seen, the pass road runs through a 72m in diameter stone circle attributed – through coin finds – to the Iron Age. It’s believed that this is the route used by Hannibal, the Carthaginian general, to invade Italy at the start of the Second Punic War in 218 BC.

From Pre St. Didier the Colle del Piccolo San Bernardo is 14.5 miles long. Over this distance, the climb is 1,184m at an average grade of 5%. The southern ramp is 8 miles long from the top of the col down to Bonneval sur Arc with an average of 7.3% descending 977m with several sections in excess of 10%.
