France and its mountains are teeming with ski resorts, some with magnificent runs. Le Petit Montagnard has selected five of them, considered to be the most difficult in France.
The Tunnel at Alpe d'Huez
This run lives up to its name. To access it, skiers must first pass through a tunnel carved out of the rock over a distance of 200 metres.
Throughout the route, "very difficult piste" signs indicate the difficulty awaiting skiers on the other side of the tunnel.
The exit offers breathtaking panoramic views for the most experienced skiers, perched at an altitude of 3,300 metres.

They will have to contend with an impressive average gradient of 70 % throughout this epic descent.
The Grand Couloir in Courchevel
The slope, reputed to be the most difficult in the 3 Vallées area, peaks at an altitude of 2,700 metres, with a total vertical drop of 340 metres.
Only the most experienced skiers can manage the 692 metres of pistes, with an impressive 85 % gradient dotted with bumps.

It requires excellent technique, because once you've started, there's no turning back. There's no way out, as this run is nothing more than a steep corridor of snow between two boulders.
La Face de Bellevarde in Val d'Isère
The famous Face de Bellevarde, Val d'Isère's fearsome black run, rises to 2,827 metres. It made history when it hosted the men's speed events at the 1992 Albertville Winter Olympics.
After tackling the 1,000 metre gradient over a distance of almost three kilometres, skiers are faced with a demanding run.

With a gradient of up to 71 % in some places, this descent represents a real technical challenge for all experienced skiers.
Le Pas de Chavanette in Avoriaz
Nicknamed the "Swiss Wall" because of its location in the heart of the Portes-du-Soleil ski area, this iconic run sits at an altitude of 2151 metres.
Its irregular surface is often compared to a field of bumps. With more than 300 metres of vertical drop, some areas reach vertiginous gradients of around 90 %.

This treacherous wall is only suitable for very good skiers, as it is very steep (37° gradient) and can have 2 metre bumps after new snowfalls.
La Sarenne at Alpe d'Huez
As well as being considered one of the most difficult runs in France, it also holds another record: the longest black run in the world, with 16km of downhill.
What makes the Sarenne so formidable is its length. While other black runs can be characterised by steep gradients and technical sections, the Sarenne stands out for its relatively low average gradient of just 12.5 %.

This black run is divided into two parts, with the first section offering steep slopes, justifying its level of difficulty, and the second part offering flatter terrain.
However, access to this part of the track is only possible after the first section, which explains its classification.
