If one climb defines the Tour de France's relationship with the mountains, it's Alpe d'Huez — 21 numbered hairpins rising from Le Bourg-d'Oisans. But Alpe d'Huez is really the gateway to something much bigger: the Oisans and Maurienne valleys hold the greatest concentration of legendary Tour climbs anywhere in the world.

The classic base is Le Bourg-d'Oisans, within striking distance of the Col du Glandon, Col de la Croix de Fer and — via the Col du Lautaret — the Col du Galibier. Saint-Jean-de-Maurienne, the "world capital of uphill cycling," gives access to the Télégraphe and Madeleine.

None of this is easy riding. Climbs here run long — 13 to 35 km is typical — with real altitude and real weather risk. But the reward is riding the exact roads that have decided Tour de France history.

Signature Routes

Col du Galibier

~34.8 km~2,069 m5.6% avg

~175 km~5,000 m

The signature challenge ride of the region: Glandon, Télégraphe, Galibier and Alpe d'Huez in one day.

Where to Stay

Le Bourg-d'Oisans is the classic base, positioned at the foot of Alpe d'Huez. Saint-Jean-de-Maurienne is the strongest alternative for the Galibier, Télégraphe and Madeleine. Briançon suits those focused on the Izoard.

Coffee & Culture

Alpe d'Huez village at the top of the climb has a good choice of cafés for a well-earned reward. Every Wednesday morning in season, a free timed mass-start event runs up Alpe d'Huez from Bourg-d'Oisans. The region's culture leans heavily on its Tour de France heritage.

Best Time to Go

June through September is the reliable core season, when the high passes are clear of snow. Pack for temperature swings of 15–20°C between valley floor and summit even in high summer.

Practical Tips

  • Grenoble is the closest airport to the Oisans valley; Lyon and Geneva both connect well with a longer transfer.
  • Some high cols close in poor weather even in summer — check conditions before setting out.
  • Descents can be long and cold; carry a packable jacket regardless of how warm the climb felt.
  • July and August bring the heaviest tourist and motorhome traffic on the main valley roads.

Climbs in French Alps

Alpe d’Huez, French AlpsFranceHors Catégorie

Alpe d’Huez

Twenty one hairpins, a balcony road above Bourg d’Oisans and a name that every cyclist already knows before they ever ride it. Alpe d’Huez is not the longest climb in the Alps, but it might be the one that feels most like stepping onto cycling’s main stage.

French Alps
Col de Sarenne, French AlpsFranceHors Catégorie

Col de Sarenne

Col de Sarenne is the quieter, sharper route into the Alpe d’Huez story. From the southeastern flank, it gives the final weekend of the Tour de France 2026 a different kind of Alpine drama.

French Alps
Col de la Bonette, French AlpsFranceHors Catégorie

Col de la Bonette

Col de la Bonette is all about altitude. With the pass at 2,715 metres and the Cime de la Bonette road reaching 2,802 metres, this is one of the great high road experiences of the French Alps.

French Alps
Col de la Croix de Fer from Allemond, French AlpsFranceHors Catégorie

Col de la Croix de Fer from Allemond

Col de la Croix de Fer from Allemond is a long Alpine climb with serious scale. It is not brutally steep throughout, but twenty four kilometres uphill is never casual.

French Alps
Col du Galibier from Saint Michel de Maurienne, French AlpsFranceHors Catégorie

Col du Galibier from Saint Michel de Maurienne

From Saint Michel de Maurienne, the Galibier is not one climb. It is a full Alpine commitment, including the Télégraphe, a brief reset and then the long road into high mountain territory.

French Alps
Col du Galibier from Valloire, French AlpsFranceHors Catégorie

Col du Galibier from Valloire

Col du Galibier from Valloire is the high mountain heart of the Télégraphe Galibier sequence. It starts after the first climb has already softened the legs.

French Alps
Col du Granon, French AlpsFranceHors Catégorie

Col du Granon

Col du Granon is a high Alpine climb with a simple message: sixteen and a half kilometres at serious gradient. It is less universally famous than Alpe d’Huez or the Galibier, but it is every bit a proper mountain test.

French Alps
Col du Télégraphe, French AlpsFranceVery Challenging

Col du Télégraphe

Col du Télégraphe is the gateway to the Galibier. On its own, it is already a serious Alpine climb. As the opening act before the giant above, it becomes even more important.

French Alps
Le Salève from Cruseilles, French AlpsFranceVery Challenging

Le Salève from Cruseilles

Le Salève from Cruseilles is short, steep and direct. At eleven percent average, it has the profile of a climb that gets serious immediately.

French Alps
Orcières Merlette, French AlpsFranceChallenging

Orcières Merlette

Orcières Merlette is a classic Alpine resort climb with a steady, race friendly profile. From the Drac valley, it rises for just over seven kilometres at a proper climbing gradient.

French Alps
Plateau de Solaison, French AlpsFranceHors Catégorie

Plateau de Solaison

Plateau de Solaison is a brutal summit finish from the Arve valley. At nine percent average for more than eleven kilometres, it belongs firmly in the hardest category.
