Apart from the sporting aspect there is not much interest in climbing the Col de la Charmette, road often in the woods, no landscape, the condition of the road is good until Pomarey then average surface, narrow and very wild road and finally it is a dead end.

Difficult climb on a quiet road. There are a few respites in the villages, but otherwise it's steep and fairly regular. The road is very straight after the last village, which makes the climb a little monotonous.
The real attraction is the descent to St Laurent du Pont via the forest road, which you can do on a gravel bike but not on a road bike.

Montée difficile sur une route tranquille. Quelques répits dans les villages mais sinon c'est raide et assez régulier. La route est très droite après le dernier village, ce qui rend l'ascension un peu monotone.
Le vrai intérêt c'est de redescendre vers St Laurent du Pont par la route forestière, faisable en gravel mais pas en vélo de route.

The beginning is nice but afterwards in the forest it starts to be long. And above all, it's a dead end, so it's better to do it on the gravel.

Le début est sympa mais après dans la forêt ça commence à être long. Et surtout c’est un cul de sac donc à faire en gravel plutôt.

I have nothing to add to sergenavetat's and achatelet's messages about the particularly sporting and demanding aspect of this climb. As far as tourism is concerned, I really like the landscape offered in the first 5-6 km. The first 5-6 km of the climb offer nice views of the neighbouring peaks (aiguille de Quaix, Pinéa, Néron).

Rien à rajouter aux messages de sergenavetat et achatelet sur l'aspect particulièrement sportif et exigeant de cette montée. Côté tourisme, pour ma part j'aime bien le paysage proposé dans les 5-6 premiers kilomètres. On a notamment des vues sympathiques sur les sommets avoisinants (aiguille de Quaix, Pinéa, Néron).

A collar that breaks the legs well, it is not too long so it is convenient to practice playing with our limits and follow our progress

Un col qui casse les pattes bien comme il faut, il est pas trop long donc c'est pratique on peut s'entraîner à jouer avec nis limites et suivre notre progression

Apart from the sporting aspect there is not much interest in climbing the Col de la Charmette, road often in the woods, no landscape, the condition of the road is good until Pomarey then average surface, narrow and very wild road and finally it is a dead end.
The 13.3km climb for 1051m of ascent has an arduous profile and is not recommended for novices.
As a warm up I advise you to start from St Laurent du Pont where you will find all the facilities (parking, toilets, shops) and to go through the small pass of La Placette which is very easy in this direction and then Voreppe (it will be a bit more difficult on the way back)
Conclusion : A rather difficult pass, I felt the high percentages but there are (fortunately) some passages to recover.
The surface is correct but it will be necessary to be careful during the descent.
The landscape is not so good.
Note that there are fountains of fresh water in the crossing of Proveysieux and Pomarey.
A lot of shade and wild road after Pomarey.

À part pour l’aspect sportif il n’y a pas grand intérêt à escalader le col de la Charmette, route souvent dans les bois, pas de paysage, l’état de la route est bon jusqu’à Pomarey ensuite revêtement moyen, chaussée étroite et très sauvage et pour finir c’est une voie sans issue.
L’ascension de 13,3km pour 1051 M de dénivelé, présente un profil ardu à déconseiller aux novices.
En guise d’échauffement je vous conseille de partir de St Laurent du Pont où vous trouverez toutes les commodités ( parking, toilettes, commerces ) et de passer par le petit col de La Placette très facile dans ce sens puis Voreppe ( il sera un peu plus ardu au retour )
Conclusion : Un col assez difficile, j'ai bien senti les pourcentages élevés mais il y a ( heureusement ) quelques passages pour récupérer .
Le revêtement est correct mais il faudra être prudent lors de la descente.
Niveau paysage c'est pas terrible.
A noter qu'il y a des fontaines d'eau fraîche dans la traversé de Proveysieux et de Pomarey.
Beaucoup d'ombre et route sauvage après Pomarey.
