Watch out for the average percentage, which is very misleading! From Lanslebourg, you first have to negotiate the Col de la Madeleine (~3.5km at 7.3%). This is followed by a long false flat climb towards Bonneval-sur-Arc before tackling the ascent.
The pass is divided into three sections, separated by two flat areas. The first 3 km are an appetiser, before the most difficult part after the first plateau. Don't forget to wrap up warm as it can get very chilly at the top. The road is good (I was expecting worse), but beware of the traffic with lots of cars and especially motorbikes (some of which pass very close by...). And beware of the marmots that can cross in front of you!

Attention au pourcentage moyen, très trompeur ! Depuis Lanslebourg, il faudra d'abord se défaire du col de la Madeleine (~3,5 km à 7,3%). S'ensuit un long faux plat montant vers Bonneval-sur-Arc avant d'attaquer la montée.
Le col se décompose en trois parties, séparées par deux replats. Les 3 premiers km sont une mise en bouche, avant la partie la plus difficile après le premier replat. N'oubliez pas de vous couvrir car il peut faire très frais au sommet. La route est bonne (je m'attendais à pire), attention néanmoins à la circulation avec beaucoup de voitures, mais surtout des motos (dont certaines passent très près...). Et vigilance aux marmottes qui peuvent traverser sous vos yeux !

A marvellous climb in a landscape that is sometimes fairytale-like. Today (15/6/2024) in Bonneval-sur-Arc the road was closed...but not for bicycles! Climbing the Iseran almost solo is a rare experience and today the huge walls of snow made it unforgettable!

Una salita meravigliosa in un paesaggio che a volte è fiabesco. Oggi (15/6/2024) a Bonneval-sur-Arc la strada era chiusa...ma non per le biciclette! Salire quasi in solitario l'Iseran è un'esperienza rara e oggi gli enormi muri di neve la rendevano indimenticabile!

Col du Mont Cenis from Susa and then Iseran for an epic day. Highly recommended.
Beware of the altitude, it can cut your legs, if you have already acclimatised a little it is better
Perfect road or many possibilities for a stop-off with refreshments

Col du Mont Cenis da Susa e poi Iseran per una giornata epica. Consigliatissimo.
Occhio alla quota, può tagliare le gambe , se avete già un po di acclimatamento è meglio
Strada perfetta o molte possibilità per una sosta con ristoro

From Bourg d'Oisans, from where we warmed up after coffee, we flew up d'Huez without luggage, first on the 42/23 but soon on to the 20 because it looked like we were pedalling in thin air after 1500km of hard work from The Hague with 20kg on the back.
Around 45 minutes we reached the top, earlier or later I don't know because we didn't have any gauges, not even a speedometer, we just counted our revolutions (42÷17) ×2.1×omw...we didn't have anything else to hand.
From the campsite along the reservoir towards la Grave where the real climbing started but the serious work only started from the Lautaret. Almost at the top the light went out completely although I should already have tasted it on my shoulders which were completely salt-free. And just like Snip and Snappie hup there I was.
Koos took his chance as eternal 2nd and stood at the top with a big smile between the snow walls.
A tablespoon of salt, water and a Gini brought me back to war strength followed by a super descent where even an A-310 had to go...Telegraphe was just a pimple and from there to a wonderfully quiet camp site de commune with a beautiful church in the village that knew the first and last quarter by heart under the light of the full moon...insane....
After breakfast we headed for d'Iseran where we steamed up in 2 hours between the wonderfully refreshing snow walls under a burning sun, 5.5% is quite distorted by the way and the descent to the authentic Val d'Isère was also a relief where we indulged in beer, coffee and crêpes, then on to Bourg St Maurice after which we continued the Roselend and Saissies to Sallanches the other day. 3000km in three weeks and legs like beech trees and jeans to Salvation Army....

Vanuit Bourg d'Oisans vanwaar we als opwarmertje na de koffie zonder bepakking d'Huez opvlogen op eerst de 42/23 maar al gauw naar de 20 want t leek alsof we in het ijle trapten na 1500km beulswerk vanuit den Haag met 20kg achterop.
Rond 3 kwartier waren we boven, eerder of later geen idee want metertjes hadden we niet, zelfs geen speedmeter, we telden gewoon ons omwentelingen (42÷17) ×2,1×omw..we hadden toch niks anders voor handen.
Vanaf de camping langs t stuwmeer richting la Grave waar het echte klimmen begon maar t serieuze werk pas vanaf de Lautaret. Bijna boven ging t licht volledig uit al had ik het al moeten proeven aan mn schouders die volledig zoutvrij waren. En net als Snip en Snappie hup daar lag ik.
Koos nam als eeuwige 2e zijn kans waar en stond boven met een big smile tussen de sneeuwwanden.
Een eetlepel zout, water en een Gini brachten me weer dra op oorlogssterkte gevolgd door een superafdaling waar zelfs een A-310 eraan moest geloven..Telegraphe was nog maar een pukkeltje en vandaar naar een heerlijk rustige camping de commune met een prachtig kerkje int dorp die eerste en laatste kwartier uit zn hoofd kende onder t licht vd volle maan..waanzinnig..
Na ontbijt richting d'Iseran waar we in 2 uur op afstoomden tussen de heerlijk verkoelende sneeuwwanden in onder een brandende zon, 5,5% is best vertekenend overigens en de afdaling naar t authentiekeVal d'Isère ook een verademing waar we ons laafden aan bier, koffie en crêpes, nog ff naar Bourg St Maurice waarna we de andere dag de Roselend en Saissies vervolgden tot in Sallanches. 3000km in drie weken en benen als beukebomen en spijkerbroeken naar Leger des Heils..

Magnificent! Done a few climbs in the maurienne valley but this one is in a different category in terms of beauty. I drove a lot by car to do this climb from lanslebourg. The plateau is really beautiful. Above the tree line it is magical and finally some dirty steep climbing. Unfortunately I had some fog on top that day so very cold and few views. The stone mini village in bonneval-sur-arc is not to be missed. You cycle right past it but it is worth a look!

Prachtig! Een aantal klimmen gedaan in de maurienne vallei maar deze is toch van een andere categorie kwa schoonheid. Heb een stuk met de auto gereden om deze klim te doen vanuit lanslebourg. Het plateau is werkelijk schitterend. Boven de boomgrens is het magisch en tot slot nog vies steil klimwerk. Helaas had ik die dag wat mist bovenop de top dus erg koud en weinig vergezichten. Het stenen mini dorpje in bonneval-sur-arc mag je ook niet missen. Je fiets er zo voorbij maar het is de moeite waard om te kijken!

In 2018 we rode up the Iseran from Bessans. The last kilometers climbing through the snow walls were unforgettable. In terms of environment and panorama's this climb is extremely enjoyable!

The climb is more about the last 13 km which is the most difficult part of this pass. The landscape is incredible and it is the highest cycling pass in France.

Montée qui se résume plus aux 13 derniers km qui représentent la difficulté de ce col. Le paysage est incroyable et puis c'est le plus haut col de vélo de France.

Done the double top... After descending from the summit to Bonneval, a quiet medieval village, we turned around and started on the difficult side. After climbing steadily through the beautiful wide green valley, you get slowly to the rough top where the last kms hurt, especially with the climb to the top from Val d' Isere already in the legs. Beautiful views and snow are the bonus.

De dubbele top gedaan... na afdaling van de top naar Bonneval, een rustig middeleeuws aandoende dorpje, zijn we daar gedraaid en begonnen aan de moeilijke kant. Na gestaag te klimmen door het prachtige weidse groene dal kom je langzaamaan naar de ruige top waar de laatste kms toch pijn deden, zeker ook met de klim naar de top vanaf Val d' Isere al in de benen. Schitterende vergezichten en sneeuw zijn de bonus.

very heavy Col if you start from Modane, from here it is just 56km up to the top but once you've reached the top you feel a real kick ;)

zeer zware Col als je vanuit Modane vertrekt , van hier uit is het gewoon 56km omhoog tot de top maar eens je deze bereikt hebt voel je een ware kick ;)

Cycled on 28/08/2020
Long quiet approach with in the beginning as a surprise some tough climbing kilometers just outside Lanslevillard
To "not the real" Col de la Madeleine. Real start after first hairpin turn in Bonneval sur Arc where afterwards nothing but natural beauty follows, especially after you entered the heart of the National Park de la Vanoise.
Dream scenery: snowy peaks, glaciers, rocks, hardly any traffic, no buildings, no ski lifts, no crash barriers, few people, beautiful waterfalls, stray animals ....
In the top 10 of my most beautiful climbs.

Practical: From Bonneval known white-yellow bicycle poles every kilometre (height/% next km./distance to top.

Gefietst op 28/08/2020
Lange rustige aanloop met in het begin als verrassing enkele pittige klimkilometers net buiten Lanslevillard
naar "niet de echte" Col de la Madeleine. Echte start na eerste haarspeldbocht in Bonneval sur Arc waar nadien niks dan natuurpracht volgt, zeker nadat je het hart van het Nationaal Park de la Vanoise bent binnengereden.
Droomdécor: besneeuwde bergtoppen,gletsjers,rotsen,amper verkeer,geen bebouwing,geen skiliften,geen vangrails,weinig mensen,mooie watervallen,loslopende dieren....
In de top 10 van mijn mooiste beklimmingen.

Most beautiful climb I've done for a while! I cycled it the day before the Tour riders, Bernal laid the foundation for his final victory there (stage cancelled) ... Beautiful Nature all around and not super hard!

Mooiste klim dat ik voorlopig al deed! Ik fietste hem daags voor de Tour-renners, Bernal legde er de basis voor zijn eindzege(afgelasten etappe)... Prachtige Natuur rondom en niet super zwaar!

Beautiful climb where you really enjoy all the views!
It is easy to do, even the length is still ok! Only the last few km you have to go deeper!
21% harder than Alpe d'Huez? Perhaps by the length then, because it goes up a few percent at most.

Prachtige klim waarbij je echt waanzinnig geniet van alle uitzichten!!
Het is prima te doen, zelfs de lengte gaat nog wel! Alleen de laatste paar km moet je wel even wat dieper gaan!
21% moeilijker dan Alpe d'Huez.?? Wellicht door de lengte dan, want het gaat hooguit een paar procentjes omhoog.

I did this last summer, amazingly beautiful climb where the whole first part 'lives' to the final climb to 2770m altitude. Totally agree with Jan, cycling in the Alps as it should be.

Deze van de zomer gedaan, waanzinnige mooie klim waarbij het hele eerste stuk 'toeleeft' naar de uiteindelijke klim naar 2770m hoogte. Helemaal met Jan eens, fietsen in de alpen zoals het hoort.

Fantastic climb from the south side. Beautiful views and certainly on the high altitudes around the top, a very 'rough' experience. It is highly recommended to climb firstly the Col du Mont Cenis from Susa, and from there on to the Iseran. As cycling fun in the Alps should be!

Fantastische klim vanaf de zuidkant. Mooi uitzicht en zeker op de grote hoogtes rond de top, een hele 'ruige' ervaring. Het is erg aan te raden om eerst vanuit Susa de Col du Mont Cenis te beklimmen, en vanaf daar door te steken naar de Iseran. Zoals fietsplezier in de Alpen hoort te zijn!
