Ski slopes are designated areas on mountains or hills where people can ski or snowboard. They are typically marked with signs indicating their difficulty levels, which range from beginner (green) to advanced (black). The slopes are groomed to provide a smooth surface for skiing, and they often have various features like jumps and rails for more experienced riders. Ski slopes are usually accessed by ski lifts, which transport skiers and snowboarders to the top. These slopes are part of larger ski resorts, which may also offer amenities such as rental shops, restaurants, and accommodations for visitors. Popular ski resorts include Aspen, Whistler, and Chamonix.
