Yellowstone National Park

Yellowstone East Entrance Access Extended to Nights

Park avalanche forecasters extended the opening times based on a continuing trend of more stable snow conditions in Sylvan Pass. They have determined that the safest travel window across the pass is during the evening and early morning hours. Forecasting staff are closely monitoring weather, snowpack, moisture and all of the complex factors that go into determining the safety of the road for public travel.

During the closure periods, the section of road between the East Entrance and a point just west of Lake Butte will be closed.

The road has been operating on a limited schedule since May 11 due to unstable snow conditions and avalanche activity in Sylvan Pass. There have been no significant slides over the road in recent days.

A limited travel window schedule is expected to remain in place until enough snow melts along and above the pass to eliminate the avalanche hazard to those traveling on the East Entrance road.

Changing weather conditions such as rain or warmer temperatures may result in conditions which may prompt changes to this schedule or may result in temporary, ‘round-the-clock closures. Travelers are encouraged to check the park’s 24-hour Road Report Hotline at 307/344-2117 for the latest updates.
