Forest Service roads remain open to legally-licensed vehicles operable on all roads in the State of Washington. ATVs do not fit this definition and must remain on designated trails and in areas specifically designated for their use in the Motor Vehicle Use Map or MVUM, which is available free at all forest offices and online at http://1.usa.gov/I4ZIDK.
All Forest Service roads closed by one foot of snow to wheeled-vehicle travel are open to over-snow vehicle use, though seasonal motorized access closures and other forest order closures do apply.
Please contact the Mount St. Helens NVM front desk at 360-449-7800 for more information.
Mt Margaret backcountry permits are tranferring to an online reservation system starting March 19th 2014. The online permits will follow the same current restrictions, yet make the application process for permits in a more available format for visitors to obtain.
