The approach from the south is very nice, the descent to the north via the forest road is not allowed, but with great caution and pushing in tunnels possible

Without wanting to be a spoilsport, it is important to remember that the Mortier tunnel is "a passage prohibited to all members of the public, failure to comply with this prohibition incurs the liability of the offender(s)," Noyarey Municipal Decree 2019/064, July 2, 2019.

To climb the Col de la Charmette you will have to cross several tunnels like this one. It is highly recommended to bring lights, because some are long.

The Col de la Charmette (1261 m) is a hidden pass within the Chartreuse Massif. The southern slope – and its three variants – is the official ascent of this pass but it can also be climbed from its northern slope. The latter is closed to traffic but... Despite its modest altitude, it is not easy to climb, you will have to face numerous steps at more than 10%!

"If you look after your bike - you carry it!" The tunnel cannot be passed on a racing bike. In addition, driving on this side of the mountain is prohibited. I sweated blood and water on the descent with the racing bike. With hiking shoes a super nice way.
