PSA Most on here are super planners to it really isn't too early to talk 2023! I am thinking about revisiting Glacier, Yellowstone and Grand Tetons in a different season - Autumn. In planning I saw there is a change to Xanterra Yellowstone reservations for
2023. Instead of opening reservations for the entire summer on one day as they have done in the past, they will go to the 13 month rolling average like they have in other parks (ie May 5, 2022 for May 1-31, 2023 dates).
The process for booking advance reservations for Yellowstone lodging, campgrounds, tours, packages, and dinner reservations will change beginning April 2022. At that time, the booking window for advance reservations will change to a 13-month rolling calendar. Specifically, on the 5th of each month, we’ll begin accepting reservations for the same entire month of the following year. For example, on April 5, 2022, guests will be able to make Yellowstone reservations for applicable dates and properties from April 1 through April 30, 2023.
