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 - 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.
