BOISE, Idaho (CBS2) — According to a Facebook post, most entrances and roads in Yellowstone National Park will be closed on Nov. 1. The last day for visitors to enjoy most of the park will be Oct. 31.

The West, South and East entrances and nearly all roads in Yellowstone will be closed to regular vehicle traffic. The park annually closes roads at this time of year to prepare for the winter season and snowmobile and snow coach travel, which begins Dec. 15.

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.

Visitors planning to drive in the park during the fall and winter should:

• Prepare for changing weather conditions.

• Have flexible travel plans.

• Expect limited services.

• Anticipate possible road closures due to inclement weather and dangerous driving conditions. Temporary travel restrictions or closures can occur at any time without notice.
