piste
A "piste" is a marked ski run or path on a mountain, specifically designed for skiing or snowboarding. Pistes are categorized by difficulty levels, typically indicated by colors: green for beginners, blue for intermediate, red for advanced, and black for expert. These trails are groomed to provide a smooth surface for winter sports enthusiasts.
Pistes are found in ski resorts around the world, where they are maintained by ski patrols and grooming machines. They are essential for organizing skiing activities and ensuring safety for skiers and snowboarders. Popular ski destinations like Aspen and Chamonix feature extensive networks of pistes.
