Snowmobiling is allowed along the 9 miles of snowmobile trails on the North Entrance Road, from the north entrance to the park all the way to the basin’s rim at North Junction, where the entrance road meets Rim Drive. Snowmobile use is limited to the unplowed roadway. The landscape is stunning, centered around the deepest lake in the U.S., Crater Lake, and the area boasts one of the largest snowfalls in the nation averaging 45 feet of snow during the winter. In fact, during some years, snowfall is registered in every month of the year. Klamath Falls is the closest Oregon city to Crater Lake.
