Tree Skiing and riding is a popular ski related activity for expert skiers and snowboarders seeking less crowded areas and fresh snow.

The SteamboatSki Resort in Steamboat Springs, Colorado is famous for its tree skiing, as are many other ski hills, including Revelstoke in British Columbia, Canada.
