What a fantastic ascent!
In the last seven kilometers, from Clavan-le-Haut,
there are stunning views,
the road is narrow and steep
and there is practically no traffic.
The only downside of this part of the climb
is the large amount of gravel on the asphalt.
The route starts in Le Clapier,
from where it runs nine kilometers on the D1091 in the direction of Briançon.
This includes a descent of 65 elevation meters
but net 300 elevation meters are gained.
After taking the side road to Mizoën, climbing becomes serious
with a one and a half kilometer section of 9-12%.
This section is followed by a descent of 30 meters,
a steeper part (up to 11%) and then again an easy passage.
So far the road is excellent.
Then, at Clavan-le-Haut the nicest part begins.
First, the road is moderately steep (mostly 7-8%)
and heads northward.
After Le Perron the road winds upward with several hairpin bends,
now taking a westerly and later a south-westerly direction
towards the pass.
This allows better views of the giants of the Écrins
(especially La Meije, 3983 meters, and the Roche de la Muzelle, 3564 meters)
which first lay behind the cyclist
but are now more or less ahead.
This part is pretty steep, 8-10% according to the profile,
but at a small scale there are steeper passages.
The col has the remarkable altitude of 1999 meters.
