Yellowstone’s South Entrance Opens To Cars Tomorrow

The South Entrance to Yellowstone National Park opens for automobile travel at 8:00 a.m. Friday, May 11, allowing spring visitors from the Jackson, Wyoming, area access to Lake and Old Faithful. The roads from the park’s North and West Entrances opened as scheduled on April 20, and the East Entrance opened May 4.

Visitors should be aware that spring in Yellowstone is very unpredictable and can still bring cold temperatures, high winds and falling snow. Even cleared sections of roads can be narrow and covered with a layer of snow, ice and debris. Drivers should use extreme caution as road clearing operations can be ongoing at any time throughout the park.

By Friday, most visitor facilities will be open at Mammoth Hot Springs and Old Faithful, and limited facilities will be available at Canyon, Fishing Bridge and Grant Village. The opening of popular campgrounds and trails, especially those in the backcountry, could be delayed. A complete list of facility and road closures can be found on the web at
