Maddalena Pass, Mountain pass and border crossing between France and Italy at Piedmont.

Maddalena Pass, or Col de Larche, is a border crossing at 1,991–1,997 metres between the Chambeyron and Mercantour-Argentera massifs, linking the Stura di Demonte valley in Piedmont with the Ubayette valley in the Alpes-de-Haute-Provence. At the crossing, a low white building with a red-tiled roof stands beside a red-and-white barrier arm, with a no-entry sign on a pole; behind it, a stone building with an arched opening sits at the foot of a square stone bell tower. The road has difficult sections on both slopes.

In 1515, King Francis I of France led his army across this pass during a campaign to capture Milan from rival powers. The crossing served as a key military route for controlling the Alpine region.

The pass carries different names on each side: Col de Larche in French and Colle della Maddalena in Italian. These dual names show how both nations have long claimed this mountain crossing as part of their own geography.

The pass is normally kept open all winter; only heavy snowfall can close it for variable periods, as in 2013-2014 (three weeks between December and January) and 2014-2015 (two and a half months). Since snow clearing was privatised on the Italian side in 2010, residents formed a "collectif du col" to monitor the situation. The road has delicate sections on both slopes, and trucks over 35 tonnes are limited to regional drivers.

The Lago della Maddalena on the Italian side marks where the Stura di Demonte river begins its journey. This river feeds into the larger Tanaro river system.
