So you’ve arrived in Chamonix and your fingers are already itching to climb. Whether you’re an experienced climber looking for indoor options, or a complete beginner fresh out of the chalk bag, this guide is for you.

Indoor climbing in Chamonix: where to start

We’ll cover the basics of indoor climbing, explain the French grading system, and introduce the main indoor climbing gyms in and around Chamonix.

Bouldering vs sport climbing

Bouldering is climbing without a rope, usually on shorter walls above thick safety mats. Falls are expected, and climbers are often supported by friends acting as spotters to help guide a safe landing.

Sport climbing uses ropes and a harness. In a top-rope setup, the rope is already fixed at the top of the route. This means you are supported at all times by a partner managing the rope below, known as the belayer.

As you progress, you may also hear about lead climbing. This is a more advanced technique where the climber clips the rope into bolts as they climb. It requires experience and good rope-handling skills.

Understanding climbing grades

Climbing grades help you choose routes that match your ability. They take into account technical difficulty, strength, endurance, and sometimes exposure or risk.

If skiing grades make more sense to you, think of it like choosing between a green piste and an off-piste descent from the Aiguille du Midi.

French grading for sport climbing

The French system uses numbers and letters, such as 4a, 4b, 4c, 5a, and so on. A “+” indicates a route that is slightly harder than the grade but not quite the next one up.

For beginners, grades between 3 and 4 are a good place to start. At the top end, the world’s strongest climbers are currently climbing routes around grade 9b.

You can find detailed explanations and comparison tables on the RockFax website.

French grading for bouldering

Bouldering grades in France use the Fontainebleau scale, often called the “Font scale”. This system is widely used across Europe and focuses on technical difficulty and movement rather than exposure or risk.
