Col de Maurin is an international high mountain pass at an elevation of 2.637m (8,651ft) above the sea level, located in the Alps, on the border between France and Italy. It's one of the highest mountain roads of the country.
The road to the summit, also known as Col de Mary, is extreme. Only 4x4 with high clearance. It’s very narrow, with deep washouts and loose gravel. The maximum gradients reach up to 20%. Impassable from September to June. This track can get very muddy and slippery after rain. At the summit there’s a mail box, probably the highest in Europe.
