A must! This climb is unique, magical and majestic too. The menu is comprehensive and incredibly varied. It's impossible to get bored for a minute! First of all, the Mercantour and this Roya valley are absolutely splendid. The village of Tende is the most beautiful starting point you could dream of for a climb.

I did Col de Tende as part of gravel round trip that included Via del Sale. Magical!!! But only doable by gravel bike or mtb. Check it out:

ERRATUM :
My previous comment concerns the Col de Tende via the departmental road 6204 and not via Slaussi.
The road is 95% the same for both climbs notwithstanding this detour via Slaussi.

But, via Slaussi, it's a bit of an adventure!
But if you're here, it's because you like to get off the beaten track.
On this route, you're in for a treat!
You can still go up through Slaussi, but the road through Slaussi was seriously damaged by storm Alex. So you have to carry or push your bike for a 300 metre stretch. It's an even wilder version of the Col de Tende. It's perfectly feasible in cyclocross mode...
The wisest thing to do is probably to avoid Slaussi.
Personally, I loved this route via Slaussi, which helps to give you an idea of what this valley has been through.
A touching moment: on the road swallowed by the waves, a stele in homage to one of the victims swept away by the storm.
I love this pass. Slaussi or not.

ERRATUM :
Mon commentaire précédent concerne le col de Tende via la route départementale 6204 et non via Slaussi.
La route est à 95% la même pour les deux montées nonobstant ce crochet par Slaussi.

Mais, par Slaussi, c’est un peu l’aventure !
Mais, si vous êtes là, c’est que vous aimez sortir des sentiers balisés.
Sur cet itinéraire, vous allez être gâtés !
On peut encore monter par Slaussi mais la route qui passe par Slaussi a été sérieusement endommagée par la tempête Alex. Il faut donc porter ou pousser son vélo sur un tronçon de 300 mètres. C’est une version encore plus sauvage du col de Tende. C’est tout à fait faisable en mode cyclocross…
Le plus sage est sans doute d’éviter Slaussi.
Personnellement, j’ai adoré cet itinéraire par Slaussi qui aide à se faire une idée de ce que cette vallée a enduré.
Moment touchant : sur la route avalée par les flots, une stèle en hommage à l’une des victimes emportées par la tempête.
J’adore ce col. Par Slaussi ou pas.

A must!
This climb is unique, magical and majestic too.
The menu is comprehensive and incredibly varied. It's impossible to get bored for a minute!

First of all, the Mercantour and this Roya valley are absolutely splendid. The village of Tende is the most beautiful starting point you could dream of for a climb.

Let's start with the bends: it's called the 46 bends route, but in reality, from Tende to the summit, there are 65 bends. All types and sizes. From the tightest to the widest. Which makes for an absolutely crazy descent!

The surface: or rather the surfaces! This is a real showroom for the Ponts et Chaussées! They show us everything that exists. From the brand new black billiard table to the rocky, nasty road over the last 4 km.
This last section is really rough and difficult to get back down. Beware of punctures.
What's more, before reaching this stretch of road worthy of the Tour de France of the 1910s, we cross a whole section of hill that is under construction for another 4 km.
It's spectacular, and you can't help but imagine the climatic tragedy this Roya valley suffered in 2020.
The scars of Storm Alex are everywhere. In our hearts, in our flesh, in our geography.
The entire Roya Valley was and still is deeply scarred by the flooding and phenomenal devastation of 2 October 2020.
All the more reason to drive here and leave a bit of money to the shopkeepers and restaurateurs who have clung on to their battered land and are having a hard time of it.

We should also mention this alternating traffic! From Tende, you are only allowed to climb the mountain during even hours. For many kilometres, the road is so narrow that two vehicles cannot possibly pass each other.

Officially, climbing the pass is reserved for residents of communes very close to the pass, and requires authorisation from the Mairie.
Cyclists are not affected by this ban and can climb the pass as long as they respect the departure times.

This is a splendid pass. You can see everything:
military forts, bunkers, sheep, patous, shepherds, backhoes, abandoned houses, varied landscapes, fabulous switchbacks...

Sleeping on the pass is also a real reward.

5 stars! Without a shadow of a doubt.

Incontournable !
Cette ascension est unique, magique et majestueuse, aussi.
Le menu est complet et incroyablement varié. Impossible de s’ennuyer une minute !

D’abord, le Mercantour et cette vallée de la Roya sont absolument splendides. Le village de Tende est le plus beau point de départ que l’on puisse rêver pour entamer une montée.

Commençons par les virages : c’est la route des 46 lacets, mais en réalité de Tende au sommet, on dénombre 65 virages. De tous types, de tous formats. Du plus serré au plus ample. Ce qui offre une descente absolument dingue !

Le revêtement : ou plutôt les revêtements ! C’est un véritable show room des Ponts et Chaussées ! Ils nous présentent tout ce qui existe. Du billard noir et tout neuf au chemin caillouteux et méchant sur les 4 derniers km.
Cette dernière portion est vraiment dégradée et difficile à redescendre. Gare aux crevaisons.
Par ailleurs, avant de parvenir à ce tronçon de route digne du Tour de France des années 1910, on traverse toute une partie de la côte qui est en travaux sur 4 autres km.
C’est spectaculaire et on essaie d’imaginer le drame climatique que cette vallée de la Roya a subi en 2020.
Les stigmates de cette tempête Alex sont partout. Dans les cœurs, dans les chairs, dans la géographie.
Toute la vallée de la Roya a été et reste encore profondément marquée par les inondations et les phénoménales dévastations de ce 2 octobre 2020.
Raison de plus pour venir rouler ici et laisser un peu d’argent aux commerçants et restaurateurs qui se sont cramponnés à leur terre meurtrie et qui en bavent.

Il faut aussi mentionner cette circulation alternée ! Depuis Tende, on n’est autorisé à grimper qu’aux heures paires. Sur de nombreux kilomètres, la route est si étroite que deux véhicules ne peuvent absolument pas se croiser.

Officiellement, l’ascension du col est réservée aux habitants des communes très proches du col et nécessite une autorisation de la Mairie.
Les cyclistes ne sont pas concernés par cette interdiction et peuvent grimper en respectant les horaires de départ.

Ce col est splendide. On y voit de tout :
des forts militaires, des bunkers, des moutons, des patous, des bergers, des tractopelles, des maisons abandonnées, des paysages variés, des lacets fabuleux…

Dormir sur le col est aussi une vraie récompense.

5 étoiles ! Sans l’ombre d’un doute.
