Boring road, though nice views and good tarmac but the cars're whizzing by. Also full in the sun

Saaie weg, wel mooi uitzicht en goed asfalt maar de auto's zoeven voorbij. Ook vol in de zon

Honestly surprised by some of the reviews on this one. Traffic is a little heavier than some of the other nearby cols. but you get great views of Grenoble and once you get over the climb you’ll be in the Vercours which are truly beautiful. This is a great option to do on a quieter day during an alpine cycling trip between days of serious climbing.

This road is very busy and not of major tourist interest. If you're coming up into the Vercors from Grenoble, it's best to take the ascent from Seyssin or Seysinnet.

Cette route est très empruntée et ne présente pas d’intérêt touristique majeur. Quitte à monter dans le Vercors depuis Grenoble, préférer prendre la montée depuis seyssin ou seysinnet.

Big, wide road with lots of traffic. The easiest way to enter the Vercors but not pleasant. The first part you cycle in the flat sun anyway, then some nice bits in the valley and then nice views once you reach the plateau.

Grote, brede weg met veel verkeer. De gemakkelijkste manier om de Vercors in te rijden maar niet aangenaam. Het eerste deel fiets je sowieso in de vlakke zon, daarna toch even wat mooie stukjes in het dal en dan mooie vergezichten als je het plateau bereikt hebt.

This long and wide monotonous and not very steep boulevard is until Lans-en-Vercors the main road access to the plateau of Lans and to the interior of the massif. It is therefore very frequented by motor vehicles and should be avoided during rush hour and during major tourist migrations... Unlike the neighbouring Saint-Nizier climb, this one does not offer any particularly spectacular viewpoints. On the other hand, due to its gentle slopes, it is a suitable climb for those who are new to mountain biking.

If the bike is solid and equipped with big tires, like "gravel", once you arrive at the Croix-Perrin pass (a welcoming inn) you can continue to the right on a forest road, unfortunately very degraded at the moment, towards the place called La Molière, about ten kilometers further, the highest road point of the Vercors (about 1600 m of altitude) with a view going up to the Mont Blanc. You can then go back down to the Mortier tunnel and Autrans.

Ce long et large boulevard monotone et peu pentu est jusqu'à Lans-en-Vercors le principal accès routier au plateau de Lans et à l'intérieur du massif. Il est donc très fréquenté par les véhicules à moteur et il est donc à éviter aux heures de pointe et lors des grandes migrations touristiques… Contrairement à la montée de Saint-Nizier voisine, celle-ci ne présente pas de point de vue particulièrement spectaculaire. C'est en revanche, du fait de ses faibles pentes, une ascension adaptée à ceux qui font leurs débuts cyclistes en montagne.

Si le vélo est solide et équipé de gros pneus, genre « gravel », une fois arrivé au col de la Croix-Perrin (accueillante auberge) on peut poursuivre à droite sur une route forestière, malheureusement très dégradée actuellement, vers le lieu-dit La Molière, une dizaine de kilomètres plus loin, point routier le plus élevé du Vercors (environ 1600 m d'altitude) avec un point de vue allant jusqu'au Mont Blanc. On peut ensuite redescendre vers le tunnel du Mortier et Autrans.
