Yellowstone Winter Access: Most Roads and Three Entrances Closed November 1, Oversnow Season Opens December 15
The U.S. National Park Service (NPS) set out Yellowstone National Park's winter arrangements on October 21: beginning November 1, the park's West, South, and East entrances and nearly all interior roads are closed to regular vehicle traffic to prepare for winter operations. October 31 was the final day to drive most park roads in 2026, including the Tower Fall to Canyon Junction road over Dunraven Pass, weather permitting.
One route remains open to cars all winter: the road connecting the North Entrance at Gardiner, Montana, with the Northeast Entrance at Cooke City and Silver Gate, passing through Mammoth Hot Springs, Tower Junction, and Lamar Valley, open year-round, weather permitting. Guided oversnow travel by snowmobile and snowcoach begins on December 15.
The park advises winter visitors that services are limited, conditions change quickly, and temporary closures can occur at any time. Travelers should check the park roads page before setting out, pack cold-weather essentials, and keep the gas tank full. Gateway communities including Gardiner, West Yellowstone, Cody, and Jackson remain open year-round. (Source: U.S. National Park Service)
