Built in the 19th century to block potential French invasions, and never used in that sense, it remains a beautiful example of military architecture, which has given its current identity to the town of Vinadio (which also has other points of interest). A visit is mandatory.

Section of the old military road with an excellent view of Vinadio and its lake. Cool and shaded, it is worth a visit.

A country centered on its fort, but which also reveals other beauties worth seeking out deliberately.

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

A splendid isolated pass accessible from Saint-Dalmas-le-Selvage, it allows an off-road ascent of the Bonette, passing through the sublime valleys of Sestrière and Sagnas to the pass itself, then via a beautiful gravel track under the north side of the Cime de la Bonette which joins the departmental road towards Jausiers, about two kilometers below the summit.

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.

One of the most beautiful ways to reach the Bonette Pass from Saint Delmas le Selvage via the Col de la Moutière. Wild and isolated, the surroundings are breathtaking. However, be prepared for a long and difficult climb.
