Route des Grandes Alpes: Bonette Pass Variant

This challenging route is approximately 96 km long with over 3,100 meters of elevation gain. While the tour data suggests a duration of around 6.5 hours, cyclists should be prepared for a full day, especially considering the continuous climbing and the need for breaks to enjoy the stunning scenery. Many experienced cyclists allocate 3-4 hours just for tackling the main cols.

No, this route is classified as difficult and is not recommended for beginners or leisure cyclists. The Col de la Bonette features continuous climbing with average gradients of 6.6% and sections reaching over 11%. It requires significant physical fitness and experience with long, steep ascents.

You'll experience spectacular high-alpine scenery, often described as 'lunar' due to its desolate, rugged appearance above the treeline. The route passes through Mercantour National Park, offering panoramic views of the French Alps, vast rock expanses, and a sense of isolation. Keep an ear out for marmots and sheep.

This route is unique because it includes the highest paved road in Europe, reaching 2,802 meters at the Cime de la Bonette loop. It's a prominent part of the legendary Route des Grandes Alpes, has been featured in the Tour de France, and offers an unforgettable high-alpine experience with its dramatic 'lunar' landscapes and historical significance.

The best time to cycle this route is typically from late June to early October, once the snow has cleared and the pass is fully open. Always check local road conditions and weather forecasts before planning your trip, as high-alpine weather can be unpredictable.

Common starting points with parking options include the towns of Jausiers (to the north) or Saint-Étienne-de-Tinée (to the south). Both offer public parking suitable for cyclists. Jausiers is a popular choice for tackling the northern ascent of the Col de la Bonette.

No, there are no specific permits or entrance fees required to cycle the Bonette Pass Variant itself. However, as parts of the route traverse Mercantour National Park, it's important to be aware of and respect the park's regulations regarding environmental protection.

When cycling through Mercantour National Park, it's essential to stay on marked roads and trails. Respect wildlife, do not disturb flora, and carry out all your waste. Specific regulations regarding dogs, camping, and fires apply within the park's core zone, so always check the official Mercantour National Park website for the latest guidelines.

While the paved roads are accessible, cycling with dogs directly on the bike is a personal choice and depends on your dog's fitness and temperament. Within Mercantour National Park, dogs are generally allowed on leash on main roads and in inhabited areas, but often restricted or prohibited in the core wilderness zones to protect wildlife. Always check park-specific regulations if you plan to bring your dog.

Yes, this route is a key part of the larger Route des Grandes Alpes. It also intersects with or runs alongside sections of other official trails, such as the 'Route des Grandes Alpes à vélo, variante Barcelonnette / Saint-Etienne-de-Tinée' and the 'Col de la Bonette (2802 m) depuis Jausiers'.

Given the high-alpine environment and challenging nature, essential gear includes a well-maintained race bike with appropriate gearing for steep climbs, warm layers (even in summer, temperatures can drop significantly at altitude), rain gear, plenty of water and nutrition, a repair kit, and a helmet. Sun protection is also crucial due to the high elevation.
