Cycling Col de la Loze from Meribel

Ride 22 kilometers (13.7 miles) gaining 1,690 meters (5,544’) at 7.7% average grade.

Note:  On September 16, 2020 (previously scheduled for July 15), Stage 17 (Grenoble - Col de La Loze) the Tour de France will feature for the first time this mountain climb. Christian Prudhomme’s Comments:

“Only a great champion will be able to win at the Col de la Loze! The stage profile invites the favourites of the Tour to be audacious. They don’t yet know the road that will take them on that day to the Col de la Madeleine and have no idea of what to expect once in the resort of Méribel. They’ll still have an extra 7 irregular kilometres to climb with several passages at over 20%.”


Stage 17 Update:  Colombia’s Miguel Ängel López won stage 17 feeling at home above 2,000 meters (his home in Colombia is at 2,500 meters).  Race leader Primož Roglič extended his advantage while López  moved into podium position at number 3.

The below Climb Summary was written by Ties Arts, Netherlands (photographs by Ard Oostra, Switzerland):

The cycling world is dynamic and so popular these days.  In Les Trois Valles in France there is an ambitious plan. A plan to connect les Trois Vallees (which includes the well known ski destinations of Courchevel, Meribel, and Les Menuires) not only via skis but also with visitors on two wheels!  The purpose is to make this very popular winter site more attractive during the rest of the seasons for cyclists.

The first step is connecting Meribel with Courchavel. And so Col de la Loze was born, with 2304m altitude.  Col de la Loze is the third highest col in Savoie area (after the well know Col de I’Iseran (2770m) and the Galibier (2642m).

Nothing beats the Col de L’Iseran for altitude, but . . .

Col du Galibier is not far behind.

Col de la Loze already existed before this plan, although the last 6 kilometers from both the east and west side were not paved.  These have been paved recently and are accessible only to cyclists - a true cyclist’s heaven!!  

There is an excellent 51 kilometer loop beginning and ending in Brides les Bains which should be done counter-clockwise to approach the col from the north.  This approach is the most difficult one, at 22 kilometers gaining 1,690 meters at 7.7% average grade (15% steepest ½ kilometer; 12.3% steepest 1 kilometer).

This is a beast of a climb with many nice hairpins saving the best for last: 8.2 kilometers at 9% after passing Meribel.

September 2019 ride report and scenic photos from PJAMM’s Ard Oostra:


Last Monday late afternoon of September 2019

Clear skies, 23 to 12C, light west wind

22 km climb to Méribel ski resort

Initial impression:  Winding roads (32 hairpins in total)  through forests, passing some villages. Wide roads, never steep, but with a fair amount of traffic for the first portion of the climb.

First segment is through villages and . . .

. . . forest . . and . . .

. . . a little bit of pastureland.

The La Loze route is indicated with road markers every kilometer, giving the average percentage for the 1 km stretch - these altitude and kilometer markers are present to the summit.

The route is easy to follow except do not miss the hairpin left turn off of D90

(Les Allues, Auvergne-Rhône-Alpes) onto Route de la Piã du Caro at kilometer 12. Just as you are about to enter Meribel.

During the first 15kms one wonders why in the world this is rated as France’s toughest climb, but this becomes painfully clear over the last third of the climb when gradients approach 20%.  

As we pass through the upper part of Méribel we begin the narrow and newly (as of 2019) asphalted former agricultural mountain road.  Over the final 7 kilometers we gain 650 meters at nearly 10% average gradient.

This is the beginning of the “bike/pedestrian only” 6 km segment.

Note:  There are official and service motorized vehicles traveling this part too.

The grades along the final segment are irregular, making it difficult to settle into a comfortable climbing rhythm.  

There are many hairpins on the climb and those along the final 7 kilometers are particularly challenging after riding 10 kilometers at about 7% into higher altitude. Blessedly, there are a couple of flatter sections leading up to the last brutal segment which do give us a brief respite - but, it these are all short-lived.

Although during the first 18 kilometers we pass through thick forest and also populated ski areas, we rise above the treeline just as we finish the steepest ½ kilometer (15.3%).  From about the 18 kilometer mark to the finish, we have for the most part unobstructed gorgeous views, particularly over the last 6 bike-only kilometers, of the surrounding Graian Alps and even Mont Blanc. Since the last segment is a ski run by winter and only a bike route by summer, we have the unique experience of passing by and under ski lifts along a path lined by snow canons.

Although this is a very popular cycling area (made all the more famous by hosting a stage finish of the Tour de l’Avenir) I encountered no true cyclists on my ascent - I was blessed to have this amazing bike climb to myself over the last 6 kilometers other than one electrified bicycle.  

At the summit are panoramic views over both Meribel and Courchevel Valleys for those fit and motivated cyclists who conquer the challenge of this most difficult bike climb.  Be sure not to miss Mont Blanc to the north-northeast - it is unmistakable at 4800 meters.

This climb is a wonderful, unique and epic experience.  

That’s a wrap!

Thank you Ard!
