So was the dining room, another grand space with Bordeaux tablecloths and plenty of windows facing the lake. The old rooms are spacious and high-ceilinged with bathrooms, and the newer 1980s rooms follow suit. There is one presidential suite. This year-round hotel, built in 1911 and finished in 1937, hints of the days when trips to Yellowstone were mostly accessible to the wealthy. The hotel and an annex behind it offer a total of 98 rooms during the summer and 136 rooms in winter.
Most rooms have two double beds, some with an occasional single, and there are two suites.
In addition to the hotel rooms, the complex has 128 cabins mostly with two double beds, but a few have an extra single. Clustered behind the Mammoth dining room and lodge, these cabins are spacious, light and airy despite their 1930s vintage. Just 5 miles from Yellowstone's North Entrance, the Mammoth Hotel is at the heart of the park's headquarters and right across the street from the Albright Visitor Center. At the other end of the building is a fast-food outlet. You can stock up on groceries and camping supplies at the Hamilton Store in Mammoth.
