"Yellowstone National Park will close its West, South, and East entrances to regular vehicle traffic starting Nov. 1. The closures allow preparation for snowmobiles and snowcoaches, which will be permitted starting Dec. 15. Not all roads will close, and travelers can enter through the North entrance in Gardiner, Montana, and the Northeast entrance in Cooke City/Silver Gate, Montana, though they should anticipate icy and snowy conditions. The park becomes a wintry wonderland offering activities like cross-country skiing, snowshoeing, snowmobiling, and wildlife watching. However, many facilities including stores, restaurants, and campgrounds close, and visitors are advised to check online for specific winter operating dates." - Alison Fox Alison Fox Alison Fox is a Travel + Leisure contributor.
