Mammoth Hot Springs Hotel can host conferences, retreats and group meetings for 30 to 350 people, with more than 9,700 square feet of meeting space and guest rooms and cabins on site. The hotel stands at Mammoth Hot Springs, in the northern part of Yellowstone National Park in Wyoming, and is run by Xanterra Travel Collection under the park's lodging concession.
Seminars and company events
The meeting space includes a board room and two conference rooms, among them the Minerva Meeting Room, named after one of the terraces of the nearby hot springs. The lodges' group team quotes meetings and events from 30 to 350 guests, so the hotel suits a company offsite, an association meeting or a scientific gathering that wants to combine work sessions with time in the park.
The setting is the main reason to come. The travertine terraces of Mammoth Hot Springs are a short walk away, and in winter daily guided tours leave from the hotel, while the Bear Den ski shop rents cross-country skis and snowshoes and runs guided outings. Few meeting venues give a group this kind of program without leaving the property.
Rooms and capacities
The website does not publish a capacity for each room, only the overall range of 30 to 350 people and the total floor area. Organisers should ask the group sales team which room fits their layout and whether rooms can be combined.
Accommodation
The hotel offers suites, deluxe rooms and several kinds of cabins: hot tub cabins, Frontier cabins, cabins without bath and two-room cabins without bath. Accessible rooms are available. The public spaces and guest rooms were recently renovated. In winter, cabins without hot tubs close, roughly from mid-October to early March, while hot tub cabins stay open. The hotel's operating season runs from April 24, 2026 to March 8, 2027, then from April 23, 2027 to March 6, 2028, dates the operator says may change.
Catering
Catering for meetings and events is provided by the park lodges. The website does not detail menus for Mammoth, so organisers should ask for the group options when they send a request.
History and setting
The hotel as it stands today was built in 1936 to plans by architect Robert Reamer, and it keeps a wing of guest rooms from 1911. It is a contributing property of the National Register of Historic Places. Its Map Room holds a large wooden map of the United States made from 15 types of wood from nine countries, a natural setting for a reception or an evening talk. Nearby, Fort Yellowstone's historic buildings and chapel recall the years when the army ran the park.
Getting there
Mammoth Hot Springs is about 5 miles from the North Entrance at Gardiner, Montana, on the only park road kept open to cars all year. The nearest major airport is Bozeman Yellowstone International. Road work on the Gardner River High Bridge may cause delays between Mammoth and Tower-Roosevelt.
