Seven Rides in the Chartreuse Alps


The other day I had a super fun ride in the Chartreuse Alps with a couple of Canadian friends. While pedalling I decided I’d write a quick article summarising several of the best routes in the region (feel free to suggest any other ride ideas).

The Chartreuse Alps is the big massif between Chambéry and Grenoble. It is home to the head monastery of the Carthusian order – Le Monastère de la Grande Chartreuse (built 1084) – famous for its Chartreuse liqueur. The region has plenty of great cycling most famously the main D512 road running through the middle of the massif from Chambéry over Col du Granier, Col du Cucheron, and Col de Porte, down into Grenoble.

Here’s a map of with seven rides. Click on a route below to highlight it.

#1 Col du Granier four Col Loop

The orange route on the map.

Starting from downtown Chambéry, this loop passes four cols: Col du Granier, Col de la Cluse, Col des Egaux, and Col de Couz.

Details clockwise here. Details anti-clockwise here.

#2 Col du Granier, Col du Coq Loop

The red route on the map.
Another four Col loop (Granier, Cucheron, Coq, Marcieu) and perhaps the most challenging ride in this article. Details here.

The distinctive shape of Mont Granier (the col is in the “bite” below) comes with a sad story. In 1248, part of the mountain effectively disappeared in perhaps the largest landslide in European history. Almost 1000 people are estimated to have been killed as a village below was destroyed. May 2016, another landslide occurred (filmed here) and has closed a couple of the routes to the Col – from via Palud and Apremont (marked on map).

#3 Col du Granier via St. Baldolphe + Col du Cucheron

The purple route on the map.
This is the ride I did the other day. The St. Baldolphe route has some very steep ramps, but is the best alternative route to the two east sides marked as closed on the map.

#4 Charmant Som via Col de Porte

The black route on the map.

From Grenoble, this route climbs to Charmant Som, the highest paved road in the Charteuse Massif via 4 Cols (Clemencière, Vence, Palaquit, and Porte). Details here.

#5 The Secret Road to Col de la Charmette

The blue route on the map.

An amazing cliff road closed to cars to Col de la Charmette. The route also climbs to Charmant Som – the highest paved road in the Chartreuse Alps – via Col de Porte. Details here.

#6 Col du Coq – the tough side

The yellow route on the map.

This east side of Col du Coq is tough. Details of a simple up/down ride here, but you could easily combine this side of Coq by riding the Granier/Coq loop mentioned above, or some sort of loop with Col de Porte and Grenoble.

#7 Col du Mollard by Mountain Bike

The brown route on the map.
A six col loop that climbs to Col du Mollard via a great, unpaved farm road. Details here.


More Monasteries

There are Chartreuse Monasteries throughout the Alps. A few ride ideas:

1. Half way up the classic north side of Col de la Colombière, in Reposoir, is the Chartreuse du Reposoir monastery. Ride details here.

2. Col de Portes in the Juras has a Monastery at the summit. Ride details here.

3. Taninges, the town at the base of several climbs has a giant chair and the Chartreuse de Mélan. See here.

Final Thoughts

The Chartreuse Alps is not the highest place in the Alps by any stretch, but it’s got plenty of relaxing, scenic cycling. Again, feel free to suggest any other ride ideas. Thanks.

  1. Hi Will,

    A fantastic summary as always! Do you know if the eastern roads up the Col du Granier via La Palud and Apremont are still closed? If so, do you have a recommended diversion for completing the red loop on your map above?

    Many thanks for all of your posts over the years, Adam

    • Not certain about the road status but “guessing” the apremont would be open. If not, the only possibility would be via St. Baldolph. In fact that purple route was – in 2016 – me surprised by the road closures and looking for a way up.

      • Thanks for the reply.

        I had a quick look at some segments going up these two routes on Strava and it seems as though there were people going up them regularly last year, so it would appear that the roads are indeed open, in the warmer months at least!
