Ski influencers claim: The best black slope is in Switzerland – “Limitless space for carving”. The Black Diamond Slope in Arosa Lenzerheide is said to have a gradient of up to 66 percent.

The slopes in Alpe d'Huez are said to be the longest in the world and to be 16 kilometers long. In contrast to the Black Diamond, 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 around the edge for relaxation breaks.
