Ski trails are designated paths on snow-covered terrain where skiers can glide down hills and navigate through various landscapes. These trails are often marked with signs indicating their difficulty levels, such as beginner, intermediate, and advanced. They can be found in ski resorts and mountainous areas, providing a safe and organized way for skiers to enjoy the sport. The design of ski trails takes into account factors like slope steepness, width, and surface conditions. Many trails are groomed regularly to maintain a smooth surface, enhancing the skiing experience. Additionally, ski trails may connect to lifts that transport skiers back to the top of the mountain.
