Our Suggested Route: Crossing the Alpine Myths (approx. 240 km)

To capture the essence of this legendary department, we propose a 5 to 6-day itinerary linking Briançon to Lake Serre-Ponçon, passing through the most famous mountain passes.

Day 1: Briançon, the Vauban City and Warm-up (approx. 30 km)

Start: Briançon. The highest town in France (1,326 m), famous for its Vauban fortifications listed as a UNESCO World Heritage site. It’s the perfect hub to explore the great passes.

The Route: To acclimate, a loop to the Clarée Valley or a gentle climb to the Izoard Pass from Cervières. It’s a day to get your legs ready, to get your body used to the altitude and admire Briançon’s unique military architecture.

The Stage: Briançon or nearby. Enjoy the evening to fine-tune your strategy.

Day 2: The Giant’s Assault – Galibier Pass (approx. 60 km)

The Route: This is the queen stage, one of the most beautiful cycling stages in the world. You tackle the legendary Galibier Pass (2,642 m). The climb is in two parts: first the Lautaret Pass (2,058 m), a long steady climb at the foot of the Meije glaciers. Then, the last 8 kilometers of the Galibier, steep, rocky, and sublime. At the summit, the panorama is breathtaking, embracing the Écrins, the Meije, and Mont Blanc. The descent to Valloire (in the 73) is fantastic before climbing back up to return.

The Stage: Lautaret or Briançon. Rest up, the achievement is done.

Day 3: The Mineral Desert – Izoard Pass (approx. 50 km)

The Route: Another legendary pass, another setting. You face the Izoard Pass (2,360 m). The climb from Briançon crosses beautiful larch forests before reaching the extraordinary site of the Casse Déserte. It’s a lunar landscape, a stretch of red cargneules and scree from which rocky pinnacles emerge. At the summit, the view of the Écrins Massif is striking. The descent to Guillestre is technical and superb.

The Stage: Guillestre. Gateway to the Queyras.

Day 4: The Queyras, Wild Jewel and Agnel Pass (approx. 60 km)

The Route: You enter the Queyras Regional Natural Park, one of the most preserved in Europe. The road follows the Guil, a turquoise river, up to the village of Château-Queyras and its fortress. From there, you tackle the Agnel Pass (2,744 m), the border with Italy. It’s a wild, long, and demanding climb, in the heart of a grand mountain cirque. At the summit, you cross into the Italian Piedmont, in an atmosphere of absolute high altitude. Turn back to return to the 05.

The Stage: Château-Queyras or nearby. The Queyras is a haven of peace.

Practical Tips for the 05

• When to Go? From mid-June to mid-September for the big passes (Galibier and Agnel are closed in winter). In July/August, start early to avoid the heat in the lower valleys and cars on the famous passes. Autumn is beautiful (colors of the larches) but the passes can be snowy.

• What Bike? A lightweight road bike with very easy gearing (triple chainring or compact with a wide cassette) is essential. A gravel bike can be an excellent option to explore the Queyras or Gapençais trails. Make sure you have excellent brakes for the endless descents.

• Accommodation: The department is well equipped with campsites, stage inns, and guesthouses. The "Accueil Vélo" label is widespread. Book in advance during high season, especially near the big passes.

• Supplies: Villages are rare and isolated, especially in high mountain areas. Always carry plenty of water (there can be long stretches without fountains) and energy bars. Don’t miss tasting the Champsaur tourtons, oreilles d’âne, and local goat cheeses.
