Les Arcs from Bourg Saint Maurice via Bois de Saule

I loved this ascent.

The first 3 km, up to Montrigon, are not spectacular (also see below). However, the following kilometers up to Arc 1600, are absolutely lovely. Lots of hairpins, nearly completely in the forest (nice if you want some shade during the summer) and very quiet. A perfect ascent if you want to ride without getting disturbed by cars. The ascent from Arc 1600 to 2000 is easier than the previous part – you cycle on wide, well-paved roads at a shallower gradient – but the fatigue may start to show. However, do continue up to Arc 2000 and the reward is a fantastic panoramic view with Mont Blanc in the distance!

Regarding the condition of the road surface: I somewhat disagree with the previous user and the data from climbfinder. The first 3km of the road, up to the village of Montrigon, are indeed not in a very good shape. However, the subsequent hairpins through the forest (route de courbaton, up to Arc 1600) are in okay shape – not better or worse than some other main roads in the area. I would not descend these routes, but for ascending at 8 to 15 kph, it is absolute fine.

The road is indeed in rough shape, but it is in a nice environment where less cars come. Overall a climb that is worth doing.
