Col de la Croix-de-Fer is one of the most famous climbs in the French Alps, known for its beautiful scenery and tough gradients. But while the climb itself is manageable for most experienced cyclists, there are sections, especially on the descent from Col du Glandon, that can be quite dangerous. In this post, we’ll explore the risks and what to watch out for on this iconic route.

Is Col de la Croix-de-Fer Dangerous to Ride?

Col de la Croix-de-Fer can be dangerous, particularly on the descent from Col du Glandon. Here’s what makes it risky:

• Dangerous Descent from Col du Glandon: Tight, steep, and technical with rough surfaces.
• Steep Sections: Some parts of the climb, especially near the top, can be tough.
• Exposed Weather Conditions: Wind and sudden weather changes at higher altitudes.

Dangerous Descent from Col du Glandon

The descent from Col du Glandon is one of the trickiest parts of the Col de la Croix-de-Fer route. Known for being steep and technical, the descent is filled with tight hairpin bends and uneven road surfaces. It requires experienced bike handling, especially at high speeds. Cyclists need to be particularly cautious in wet conditions, as the road can become slippery and the steep gradients make braking more difficult.

In addition to the technical difficulty, there are several rough patches on the road with cracks and loose gravel, especially after a harsh winter. These obstacles can throw off your balance or puncture your tires, making this section of the ride especially hazardous if you’re not cautious.

Steep Sections

While the climb to Col de la Croix-de-Fer is generally considered fair for seasoned cyclists, there are steep sections, particularly near the summit, where gradients can exceed 10%. These sections are tough but manageable if you pace yourself and are prepared for sustained climbing.

The main danger during the climb is fatigue, which can make handling your bike more difficult. If you’re not used to long, challenging climbs, this ascent could wear you down before you reach the summit. It’s important to stay well-hydrated and pace yourself to avoid exhaustion before reaching the top.

Exposed Weather Conditions

As with many high-altitude climbs in the Alps, Col de la Croix-de-Fer is exposed to the elements. Wind can be particularly fierce, especially on the upper sections. Sudden weather changes are common, and the temperature can drop significantly as you ascend. While not inherently dangerous, poor weather conditions can make the descent, especially from Col du Glandon, far more treacherous.

Before your ride, always check the weather forecast and be prepared with the right clothing to stay warm and dry. High winds can make the descent feel even more dangerous, so it’s important to stay focused and keep your speed in check.

Conclusion

Col de la Croix-de-Fer is generally a fair climb for experienced cyclists, but the descent from Col du Glandon is notoriously dangerous. With tight corners, steep gradients, and rough road conditions, it’s not a section to take lightly. The climb itself can be challenging, but with proper pacing and preparation, it’s manageable for most riders. Always stay cautious, especially when descending, and make sure you’re prepared for changing weather conditions at higher altitudes.
