Yellowstone National Park’s Mammoth Hot Springs Hotel and Cabins will open on July 1, 2023. The hotel closed immediately after the historic 2022 flood because of damage to the area’s wastewater system.
The hotel gift shop with sandwiches, snacks, and beverages and lobby are currently open. The Terrace Grill, with sandwiches, salads, ice cream, and beverages, is currently open for lunch and dinner. Breakfast hours will begin on July 2.
The hotel dining room will open at a later date.
All tours departing from the Mammoth Hotel will begin on July 1.
In June 2022, unprecedented amounts of rainfall caused severe damage to the North Entrance Road between Mammoth Hot Springs and the park’s North Entrance in Gardiner, Montana. In addition, a sewer line adjacent to the road that carried wastewater from Mammoth Hot Springs to a sewage treatment plant in Gardiner was ruptured. Staff quickly rerouted the wastewater into percolation ponds used between the 1930s and 1960s, allowing day-use visitors and residents to stay in the area.
In just a year, a new wastewater treatment system has been built and is now operational. The system serves the Mammoth area, including the hotel and campground. The Mammoth Campground will open once it is repaired and connected to the new system.
The hotel was originally intended to open on June 16, but delayed as the new system was not completely finished.
This is excellent news for tourists and Park County residents, as lodging tax is collected from all reservations at Mammoth Hot Springs Hotel.
Xanterra, the hotel concessioner, is in the process of notifying guests with reservations about the good news. Visit operating hours and services for updates on the Mammoth Hot Springs Hotel and Campground.
