The latest hot spot?
The 2026 Tour d’Auvergne-Rhône-Alpes, the 2026 Tour de France, and the 2027 World Cycling Championships! The Tour has already visited here in 2021, but this will be the first time that Solaison hosts a stage finish and a stage victory that will be decided on this plateau.
A road that’s been completely resurfaced for these events.
This cliff-side road is, first and foremost, intrinsically magnificent. But now it’s like a freshly waxed billiard table – even the mosquitoes would slip on it.
A real treat! And the descent is absolutely mad!
The bends and turns are incredibly varied.
The rocks are imposing and the views are often spectacular.
Are we really going to get into the gradients?
This pass is tough and demanding. The first section is gruelling and difficult but fairly steady. You eventually find your rhythm. After Brison, you’re tossed between gradients of 8 and 11 per cent, with some sections even steeper.
At the top, there’s no exceptional reward: the scenery is pleasant but not magical.
There’s even a football pitch… A football pitch on a mountain pass? It’s not a pass, it’s a plateau, a proper plateau. But not as boring as the Langres plateau…
The atmosphere is very pleasant. Blueberry tart, Savoyard fondue and a Reblochon casserole round off the potato galettes.
Lots of cyclists. From all over.
If, like me, you’ve had a right old slog, do what I did: settle down in a pretty spot with a steep gradient and wait for the other cyclists. Everyone seems to be struggling on this pass.
It lifts your spirits…
In short: it’s a tough climb, a really tough one. The road is absolutely stunning. As I was climbing, I’d built it up too much in my mind, expecting a finish against a spectacular backdrop, but it’s just beautiful…
A must-do! Without a doubt.
Have a blast on the descent. But not into a rock. Watch out: it really does tempt you to ride fast.
Oh yes: Seixas mania has taken the area by storm! Here, people declare their love for Paul at every bend. Impressive!
La nouvelle montée en vogue ?
Tour Auvergne Rhône-Alpes 2026, Tour de France 2026, Championnats du monde de cyclisme 2027 ! Le Tour est déjà venu ici en 2021, mais ce sera la première fois que Solaison accueillera une arrivée et une victoire d’étape qui se dénouera sur ce plateau.
Une route refaite à neuf pour ces événements.
Cette route des falaises est d’abord intrinsèquement magnifique. Mais, à présent, c’est un billard fraîchement ciré sur lesquels même les moustiques glisseraient.
Un régal ! Tout comme la descente est folle !
Les courbes et virages sont ultra variés.
Les roches sont imposantes et les vues sont souvent spectaculaires.
On aborde vraiment la question des pourcentages ?
Ce col est costaud et exigeant. La première partie est lourde et difficile mais assez régulière. On finit par trouver son rythme. Après Brison, on est ballotté entre du 8 et du 11%, avec des passages plus épicés encore.
À l’arrivée, il n’y a pas de récompense exceptionnelle : les paysages sont harmonieux mais pas magiques.
Il y a même un terrain de foot… Un terrain de foot sur un col ? Ce n’est pas un col, c’est un plateau, un vrai plateau. Mais pas chiant comme le plateau de Langres…
L’ambiance est très agréable. Tarte aux myrtilles, fondue savoyarde et cassolette de Reblochon complètent les galettes aux patates.
Beaucoup de cyclistes. Venus de partout.
Si comme moi, vous en avez bavé, faites ce que j’ai fait : posez vous dans un endroit joli et bien pentu et attendez les autres cyclistes. Tout le monde semble souffrir sur ce col.
Ca remonte le moral…
En résumé : c’est une montée solide, très solide. La route est très belle. En grimpant, j’avais trop misé sur une arrivée dans un décor grandiose et c’est juste beau…
À faire ! Sans hésiter.
Éclatez-vous dans la descente. Mais pas contre un rocher. Gaffe : c’est vraiment une invitation à rouler fort.
Ah oui : la Seixas mania a contaminé la zone ! Ici, on déclare sa flamme à Paul à chaque virage. Impressionnant !
Left Villaz on a misty morning to tackle Col de Solaison through Thuet and as you start the climb and gradually move down through the cogs of the cassette and settle down to the relentless 10％+ gradient of the first 10 kilometres keeping your cadence as fluid as possible viewing the stunning scenery and the drop to the valley below. Finally you have a little respite as the gradient decreases for a few kilometres before reminding you that the Solaison is a climb of substance with another kick up in gradient before leveling out at the top and then you can relax with the knowledge and satisfaction of your real achievement in tackling this great climb. I would recommend if you are a senior like myself to have at least a 32T cassette with your compact to ease the strain of those relentless gradients.
The first part between Thuet and Brizon is steep and steady. The second part (after Brizon) is less regular and more of a challenge. Once you reach the top, it's time to order the potato fritters!
C’est raide et régulier dans la première partie entre Thuet et Brizon. Dans la deuxième partie (après Brizon) c’est moins régulier et plus casse patte. Une fois arrivé en haut, c’est les beignets de patates qui faut commander !
Everyone summed it up well - beautiful views, not a lot of cars, and steep mostly consistent climbing on nice roads. It’s a winner.
I would not be surprised if it is in the Tour de France in the very near future, as they have already finished there several times in the Dauphine. As recently as 2022, Vinjegaard won here ahead of Roglic. It is a beautiful and challenging climb. The first 3.5 kilometres in the forest with percentages above 10％, then the cliff road, which you can already see from the motorway, then slightly flatter through Brizon and, as a dessert, the last 5 kilometres to the plateau, where little by little it gets flatter. Especially the cliff road part is beautiful, but also on the plateau you have nice views and here and there you'll find nice flowers along the road.
Het zou me niks verbazen als deze in de zeer nabije toekomst in de Tour de France zit, aangezien ze er al meerdere malen zijn gefinisht in de Dauphine. In 2022 won Vinjegaard hier nog voor Roglic. Het is een mooie en uitdagende klim. De eerste 3,5 kilometer in het bos met percentages boven de 10％, daarna de cliff road, die je vanaf de snelweg al kunt zien, daarna iets vlakker door Brizon en als toetje de laatste 5 kilometer naar het plateau, waar het beetje bij beetje steeds iets vlakker wordt. Vooral het cliff road gedeelte is mooi, maar ook op het plateau heb je mooie vergezichten en staan er hier en daar leuke bloemen langs de weg.
Well known to local cyclists and final of the last stage of the Critérium du Dauphiné Libéré 2017, the climb to the Solaison plateau via Thuet is a very steep climb as the gradient over 11kms is over 9 ％
So it is better to arrive at the foot after a good warm up.
From the start the road rises sharply and moments of respite will be rare, a passage before the village of Brizon allows you to catch your breath before the 2nd part which is more irregular with passages at more than 10 ％ including one at 15 ％
Many areas in the shade ( in the morning) , I did not see any drinking water point.
The finish is on the huge plateau of Solaison, the start of many hiking trails and where you can taste the local specialty at the restaurant La Bruyère : the famous potato fritters.
For information: The cycling signs are present at each kilometer
Bien connue des cyclistes du coin et final de la dernière étape du Critérium du Dauphiné Libéré 2017, la montée au plateau de Solaison par Thuet est une ascension très raide puisque la pente sur plus de 11kms est supérieure à 9 ％
Il vaut donc mieux arriver au pied après un bon échauffement.
Dès le départ la route s’élève brusquement et les moments de répits seront rares, un passage avant le village de Brizon permet de reprendre un peu de souffle avant la 2ème partie plus irrégulière avec des passages à plus de 10 ％ dont l’un à 15 ％
Beaucoup de zones à l’ombre ( le matin ) , je n’ai pas aperçu de point d’eau potable.
Le final se situe sur l’immense plateau de Solaison, départ de nombreux sentiers de randonnées pédestres et ou vous pourrez déguster la spécialité du coin au restaurant La Bruyère : les fameux beignets de pommes de terres.
