The West, South and East entrances and nearly all roads in Yellowstone National Park will be closed to regular vehicle traffic November 1st. The park annually closes roads at this time of year to prepare them for the winter season and snowmobile and snowcoach travel, which will begin December 15. The last day for visitors to drive most park roads will be October 31.
The only roads open year-round are between the North Entrance in Gardiner, Montana, and the Northeast Entrance in Cooke City/Silver Gate, Montana (via Mammoth Hot Springs, Tower Junction and Lamar Valley).
