Roads to Ride: the Lacets de Montvernier

Lacets Monvernier

New for the 2015 Tour, this is Hairpin Heaven. Alpe d’Huez might be famous for its 21 bends but here’s a road with 18 hairpins in short formation. One bend follows another, a helter-skelter for the road cyclist and just a short spin away from some of the famous climbs of the Tour de France. But is it as good as it looks?

The Route: the D77B starts in Pontamafrey-Montpascal in the Savoie department of France. The road heads north to Montvernier. The climb is 3.8km long and averages 8%.

The Feel: the sign at the start says Montvernier is 8km away and you should turn the right. Ignore it. Take the road with the small cyclotouriste sign for the Lacets de Montvernier. Lacet is French a loop or hairpin bend and it’s not like you need signs, maps or GPS to spot the tarmac garland winding down the mountainside above you.

The road climbs past a few houses and then heads straight for the hairpins. Listed as four kilometres long, the bendy section is concentrated within a 2.5km stretch meaning a bend every 150 metres. This is the steepest part.

Alpe d’Huez’s hairpins are wide, gentle and engineered so that tourist coaches can pass each other on the bends. Here large vehicles are banned and if a cyclist and car meet each must check their line. The road is narrower and cut into the rock face. Being south-facing the rock walls radiate heat back in summer.

You’ll lose count of the corners, there are no numbered bends, but you can sense the end is coming as you get higher and then the road passes below a small chapel and then heads in to a plateau. The mistake is to think the climb is done. Once the bends are over it rises through pastures and this section is a bit deflating, hard work without the views and corners to aim for. Press on for a kilometre and you reach Montvernier where there’s a fountain to top up your bottles.

The Verdict: for all the seductive images and curves, this is a road that looks better from afar, especially a TV helicopter shot when there’s a big race snaking up. It’s like looking at a Rembrant, by all means enjoy the detail but you need to stand back to appreciate the full picture.

When climbing you’re so close to the cliff face that you lose the perspective. But you gain in other ways, notably the feel of the road. At four kilometres this can’t be sprinted up but it’s worth scaling as fast as you can in order to feel mild G-force on the bends as your arms tighten on the bars and it does feel faster than it should. Unlike the nearby Alpe d’Huez you can do one bend and then aim straight to the next; unlike Alpe d’Huez the bends offer no respite, the road climbs upwards through the corner.

Downhill: to descend is different, the corners come so fast that it becomes very technical. Unlike other Alpine descents a high speed is impossible, this is all about braking and cornering. It’s more reminiscent of the Poggio with the brake-corner-sprint reps, only longer and the surface is rougher.

History: the road dates from 1934. The Col du Ventour to the south-east allows traffic reach to the plateau and the construction of this winding route seems absurd, although equally impressive, but visitors are all the better for it. Over the years it’s gained a reputation amongst cyclotouristes as a road to tackle but I can’t find a trace of a major race using the road.

Travel and Access: this isn’t a remote climb, it sits next to famous Tour climbs like the Col de Madeleine, the Col de la Croix de Fer and the Col du Glandon, all within a short spin and a little further up the valley is the mighty Col du Galibier via the Télégraphe. In other words if you’re in the area for one of these big cols, here’s an ideal rest day spin, a thrill instead of an epic ride.

The town of St Jean de Maurienne is a good enough place – FDJ have a deal with the town as their Alpine base – but remember the main valley road is busy and at times industrial so climb to get away from it all. It can all be reached by train and autoroute and the end of the valley marks the border with Italy via either the Fréjus tunnel or the Col du Mont Cenis meaning it’s within reach if you’re visiting the Val di Susa and Sestriere too.

    • It is a great climb, you can make an create a little circular tour by starting in St Jean de Maurienne, reach the top of the hairpins and continue on a good road to the the Col de Chaussay (1532m), then on a rather rough forestry road for a couple of kilometres, back onto a decent road and come out on the Madelaine road a few kilometres up. Turn left, back to the main road and the to St J de M.

      Enjoy, I did!


  1. I did it last summer. Was at work, actually, invited by Focus bikes. I found it fantastic, even more so by the transition to the pastures above the chapel and the horrible straight section cut into the rock face further up.

    A must ride if your’re in the area, maybe as an aperitif to your Madeleine day.

  2. A road to ride? Yes, definitely. While the “lacets” alone are fun to climb the real reason to ride them is to continue that climb all the way up to the Col de Chaussy which I found marvelous. The road belongs to you. The descent on the other side down to the Col de la Madeleine ramp (the D213) is perfectly paved since 2012. When reaching the D213 you can continue the descend or climb up the missing 1200 meters to the Madeleine and then go down to the same valley but on the parallel road over Montgellafrey.

      • Love this climb. And agree. These great hairpins are actually a short climb. While Chaussy is quite a large climb …. and Madeleine then beckons.

        Another suggestion: after climbing Les Lacets and Col du Chaussy, one can get to summit of Col de la Madeleine more directly on a fantastic unpaved farm road that passes Lac du Loup (Wolf Lake) and after several kms crosses into the madeleine valley and joins the Madeleine main road above Longchamps. Quiet, scenic, fun.

        Details here:

        Separately: If you want to photo the Lacets de Montvernier it is almost impossible to get an interesting photo while on or above the hairpins. Instead, when you finish them and the road flattens …. just below the little chapel …. head into the field to the right, follow a path perhaps a half kilometre over the field and then into the woods … then you will get to a cliff and a clear view. this is where the top photo in The Inner Ring’s article was taken.

        • Hi Will,

          the unpaved road you recommend is quite entertaining and scenic. And there is absolutely no traffic but I would certainly not recommend doing it on a road bike. I mean I did it with some friends and we had no puncture but it features sections of deep gravel with big stones where you have to ride really carefully to prevent cutting your tires. And the last km on that road when you actually descend onto the Madeleine road some 2 km beneath the col is definitely too rocky to descend it on a road bike. You know why you choose your trekking bike for that road.

  3. On the San Boldo question. Yes. great ride, Little traffic and fun. However relatively easy, but it is possible to Combine it with other climbs in that area. Obviously monte Grappa is “The” Climb in that Area of Italy.

  4. I did it in august 2012. Great climb but very hot on the “lacets” of Montvernier (as I remember). And then Col de Chaussy, the road belongs to you: calm, nobody else, peaceful… Totally différent of Madeleine, Galibier,… Great to end a week in Saint-Jean de Maurienne 😉

  5. Inrrng,

    A tourist’s question regarding riding in France, the towns, even in Paris, appear to have some fountains with a little water running in public squares or even alongside some public-facing wall of a building.

    Is there some way to distinguish where it’s appropriate to grab some water from these quietly-running spigots?

      • You will also find eau non surveillee, especially in the Alps I’ve found.
        It seems to be more common now, and is a basic disclaimer that the water source isn’t monitored – I’ve never had a problem with these fountains but you take your chances, especially on a hot day when 2 or 3 climbs have passed and several villages, each of which have all had non potable water

  6. I rode this climb in 2012, coupling it with the Madeleine shortly after the west side was paved. Yes, the col is as good as it looks, because even once the first three km of tight hairpins are over you get beautiful views of the Aiguilles d’Arves across the valley, and further up a section of road etched into the cliff somewhat like the cols of the Vercors near Grenoble. As a bonus, about 5 km down the Madeleine side, the Auberge du Bon Coin is a nice place to stop for refreshments, and the proprietor dispenses cereal bars to cyclist customers.

  7. ah i thought this was the madelaine as i’m sure it comes up when you google it, i have ridden the madeleine and thought ‘eh it doesn’t seem like that climb on google images’, this explains it!!!
