Find everything you need to know about making direct reservations for all in-park lodging and camping in Yellowstone National Park. We never charge a booking fee for any Yellowstone reservations.
We also manage and maintain the in-park facilities for which we take reservations. We are committed to helping you find your ultimate Yellowstone experience, while working to protect and preserve the park for the future.
In our efforts to continually improve and care for the facilities we’re privileged to operate, there will be several projects in progress during the 2016 summer season. With such a short window for accomplishing this type of work, it often must be done while guests are in-house. We regret any inconvenience this may cause and thank you for your understanding.
Renovations of Exterior and Interior Public Space
– Ongoing renovations of the hotel exterior and interior public spaces will require staging of equipment and materials and construction activity around the exterior of the Mammoth Hotel building to continue throughout 2017.
While the Mammoth cabins, restaurant and Terrace Grill will remain open during the summer season, Mammoth hotel rooms, hotel public spaces and gift shop will not be accessible.
Concrete, curb and gutter work
– is planned for around the front of the lodge. The project will start when weather allows, and will take one month to complete.
The paving of cabin loop roads and parking lot
– is scheduled to begin in June/July as weather and temperatures allow.
RV dump station replacement. Scheduling of work yet to be determined.
Paving scheduled for later in summer, though loops will be closed and off line during the process so that the work is happening in unoccupied areas.
