The most beautiful MTB and hiking tours in the French Maritime Alps
I rode up to the Col de Moutiere from Saint Etienne via Saint Dalmas, and then took the 3km of gravel road link to the Col de la Bonette. I returned to Saint Etienne via the more classic D64. It makes for a much quieter, wilder and steeper ascent, with a better (but busier) road surface and more gradual decline for the D64 descent. Also this way it's a loop and you see more of the incredible scenery. The 3km gravel section is very doable with my moutain bike (i would rate it as a 'blue'). I didnt need to carry or push the bike even though some parts were boken up by small water crossings. I was overtaken by a motorbike at one point. Be careful of the weather here, especially the potentially violent afternoon thunderstorms. There is no shelter nearby

If there were a ranking of the most beautiful, undiscovered Alpine passes in the cycling world, the Moutière would certainly be a contender. Starting from Saint-Dalmas-le-Selvage, the climb through the valleys of Sestrière and Sagnas is simply sublime.

The Col de la Moutière is located in Provence-Alpes-Cote d'Azur. This climb is part of the Alps. From Saint Etienne de Tinée, the Col de la Moutière is 18.3 km long. Over this distance 1300 altimeters are bridged. The average slope of the rise is, therefore, 7.1%.

Located west of Mont Bego and at more than 2,000 m above sea level, the Vallée des Merveilles offers the austere beauty of a mineral and chaotic landscape, at the foot of imposing peaks reflected in multiple lakes with evocative names. There are particularly emblematic engravings, depicting themes that combine everyday life and beliefs. On the eastern slope of Mount Bego, the Fontanalba valley shows its engraved rocks in an open and welcoming place where the flora reveals all its richness. The engravings illustrate the pastoral life of the first shepherds of the Neolithic and Bronze Age, as demonstrated by the famous “sacred path”. Classified as a Historical Monument since 1989, the archaeological area of the Mont Bego rock engravings, straddling the two valleys, offers numerous discoveries, both historical and landscape, natural and cultural: welcome to one of the largest rock engraving sites in Europe . !

During these months, the weather is milder, trails are more accessible, and the alpine flora is in bloom.
