A Ski Resort, as the name suggests, is a resort developed for skiing and other winter sports. In Olympic Valley, a ski resort is a town or village in a mountainous area, where ski trails and supporting services, such as hotels and other accommodations, restaurants, equipment rental and a ski lift system, are available. Ski areas have marked paths for skiing, known as runs or trails. Some ski resorts offer lodging options on the slopes themselves, with ski-in and ski-out access allowing guests to ski right up to the door. Ski resorts often have other activities, such as snowmobiling, sledding, indoor or outdoor swimming, game rooms, and local forms of entertainment, such as clubs, cinema, theatre and cabarets.
