Ski influencers claim: The best black slope is in Switzerland – “Limitless space for carving”. The Black Diamond Slope in Arosa Lenzerheide has a gradient of up to 66 percent.
The black piste in Alpe d'Huez is said to be the longest in the world and to be 16 kilometers long. It is partly narrow and not only steep, but also a mogul slope. And it is so long that camping tables have been set up along the edge for relaxation breaks.
