🚴‍♂️ The most beautiful mountain passes to cycle from Alpe d’Huez: complete guide

🏔️ Col de Sarenne: wild and secluded

The Col de Sarenne is often considered one of the Oisans region’s best-kept secrets. Less well known and far more secluded than the major neighbouring passes, it offers a unique experience, away from the crowds and close to the raw beauty of the mountains. The Col de Sarenne is especially appealing for its rugged character. Quiet and unspoilt, it crosses preserved Alpine scenery of pastures, streams and isolated summits.

Why ride it?
Less busy than the major Alpine passes, it offers an authentic experience with raw, unspoilt landscapes.

Practical information :

• Altitude: 1,999 m
• Distance from Alpe d’Huez: 10 km
• Elevation gain: moderate but irregular
• Road: narrow, sometimes in poor condition

👉 Ideal for lovers of peace, quiet and wild nature. In summer, it is not unusual to come across grazing herds. Watch out for guard dogs. If you see one, even from a distance, get off your bike and walk calmly beside it until you are safely away.

🍽️ Feeling peckish? At the pass, you will find a traditional mountain hut serving local produce platters with cheeses and cured meats. You can also enjoy juice and cold drinks there.

🌄 Col d’Ornon: accessible and pleasant

The Col d’Ornon is perfect for a gentler outing. It is often regarded as one of the most accessible passes in the Oisans. Less dramatic than its neighbours, it is still an excellent option for an enjoyable ride through a calm, green environment of hamlets, dense forests and Alpine meadows.

Why ride it?
It is a steady, accessible pass, ideal for an active recovery day, for getting started in the mountains, or for an endurance ride.

Practical information:

• Altitude: 1,371 m
• Distance from Alpe d’Huez: 22 km

🍽️ Need a snack or a good lunch before heading off again? Stop at the Auberge de Chantelouve, where you will be welcomed by Camille, Sarah and Théo. In season, the restaurant is open every day from 9 am to 10 pm, with daily menus and à la carte dishes. Everything is homemade using organic, local meat. Picnic baskets are also available.

⛰️ Col du Glandon: an irregular challenge

The Col du Glandon, linking Isère and Savoie, and featured in both the Tour de France and La Marmotte, is a classic of Alpine cycling. It is a must for cyclists looking for a challenge in the Alps. Less publicised than some of its neighbours, it is still formidable thanks to its unusual profile and constant changes of rhythm.

Why ride it?
Its irregular profile makes it a real tactical challenge.

Practical information:

• Altitude: 1,924 m
• Distance from Alpe d’Huez: 53 km
• Long climb with changes in gradient
• Light traffic on some sections
• Often paired with the Croix de Fer
• Scenery: narrow valleys, open pastureland and a more mineral high-mountain atmosphere near the top

The final approach is particularly beautiful, with a growing sense of remoteness and altitude.

👉 Ideal for working on rhythm, endurance and coping with irregular gradients. Expect alternating flatter sections and steeper ramps, easier stretches followed by demanding ones, and increasing difficulty as you approach the summit.

⚠️ Please note: the road over the pass is only open in summer, from June to October.

🌞 Col du Lautaret: grand panoramas

The Col du Lautaret is one of the most accessible passes in the Alps, but also one of the most spectacular. Located between the Oisans and the Guisane valley, it is often an essential stop before tackling the legendary Galibier. It is one of the Oisans region’s must-rides, renowned for its steady gradient and exceptional panoramas. It is one of the few Alpine passes above 2,000 metres that can be reached without extreme difficulty, making it ideal for many cyclists.

Why ride it?
It offers spectacular views of the glaciers, especially La Meije, and the surrounding peaks.

Practical information:

• Altitude: 2,058 m
• Distance from Alpe d’Huez: 51 km
• Regular gradient (around 4%)
• Wide, well-maintained road
• Busy route: watch out for traffic

The Col du Lautaret is a major road linking Grenoble and Briançon. As a result, traffic can be heavy, especially in summer. It is advisable to set off early in the morning to enjoy quieter conditions.

👉 Perfect for a long but steady climb. It is an excellent pass for building endurance or for a first experience of high mountains.

🛌🏼 A tip? Spend a night at the Lautaret Lodge & Spa, better known as the Hôtel des Glaciers. A true institution, with a slightly Shining-like atmosphere when the mist rolls in.

🍴 For an energy boost, nothing beats the hiker’s bar from the Atelier du Lautaret: a richly flavoured gingerbread with honey, orange peel, lemon peel and plenty of almonds.

🌿 Worth visiting! For more than 100 years, the Jardin du Lautaret has maintained and preserved a vast collection of 2,000 mountain flower species from around the world, in an exceptional landscape facing the glaciers of La Meije.

🏆 Col du Galibier: a cycling legend

The Col du Galibier is one of the most famous passes in the world and one of the great icons of global cycling. Made famous by the Tour de France, it is a real challenge for any cyclist, both because of its altitude and its physical demands.

From Le Bourg-d’Oisans, the ascent of the Galibier is divided into two very distinct parts. The first leads to the Col du Lautaret, with a regular gradient that allows you to manage your effort. But the real difficulty begins after that. The final 8 kilometres to the summit are much more demanding.

Why ride it?
It is a legendary climb: demanding and spectacular.

Practical information:

• Altitude: 2,642 m
• Distance from Alpe d’Huez: 52 km
• Significant elevation gain
• Final section very demanding
• Often snow-covered out of season
• Scenery: 360-degree panoramic views and a strong feeling of isolation in a high-mountain setting

👉 The weather can change quickly. Even in summer, temperatures at the summit can be very low. Make sure you bring the right kit.

🚵 Col de la Croix de Fer: long and majestic

The Col de la Croix de Fer is an Alpine giant. It is one of the great legendary passes of the Alps. Long, varied and demanding, it offers a complete experience combining endurance, pacing and the pleasure of spectacular scenery. Renowned for its length and the variety of its profile, it is a full challenge for cyclists looking for a demanding and immersive ascent.

Why ride it?
Its length and varied scenery make it a complete adventure.

Practical information:

• Altitude: 2,067 m
• Distance from Alpe d’Huez: 50 km
• Progressive but demanding climb
• Often combined with the Glandon
• Scenery: narrow valleys at the start, open Alpine pastures, and a more mineral landscape near the top

👉 Ideal for a big endurance ride. The climb is long, nearly 30 km depending on the route, fatigue can build up with the changes of pace, and mountain weather can be unpredictable.

🍴 On the descent, take time to stop at the Chalet du Col de la Croix de Fer, by the roadside, with its view of the Aiguilles d’Arves and the Aiguilles d’Argentières. You can have lunch there, simply enjoy a drink, or treat yourself to a sweet snack with crêpes, waffles and organic apple juice.

🌿 Col du Sabot: short but fearsome

The Col du Sabot is a little-known but intense challenge. It is one of the hardest and least frequented passes in the Oisans. Little known to the general public, it is nevertheless formidable because of its gradient and constant effort, making it a real test for climbers.

Why ride it?
Its steep, constant gradient makes it an excellent test of power. It is one of the hardest passes in the region.

Practical information:

• Altitude: 2,100 m
• Gradients often above 10%
• Narrow, lightly used road
• Exceptional view from the summit

👉 Perfect for climbers who enjoy short, intense efforts. From the very first kilometres, the slope is striking: a direct ascent with no real transition, sections constantly above 9–10%, and very few places to recover.
