You must have a valid Sno-Park permit displayed in the windshield of your vehicle if you park in a designated winter recreation parking area (Sno-Park) between November 1 and April 30. Each of these areas are posted with signs identifying them as a WINTER RECREATION AREA. You will find Sno-Parks in all mountain passes of the state as well as most recognized ski, snowmobile, and snow play areas. Oregon-s Sno-Park Program is funded entirely by the sale of Sno-Park permits. The program provides funds for snow removal in Sno-Parks and enforcement of the permit requirement. Any money remaining may be used for maintenance and development of Sno-Parks or carried over for use in a following year.
