Mammoth Hotel Rooms Renovation Project
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 2019 summer season. With such a short window for accomplishing this type of work, it often must be done while guests are in-house.
At Mammoth Hotel, Phase 2 of the NPS renovation project, targeting the guest room wings of the hotel, began in early September of 2018 with staging of equipment behind the hotel. The guest cabins, dining options, Map Room/lobby and gift shop will remain open through the regular summer season.
Special note to arriving and in-house guests: The front desk and lobby of the Mammoth Hotel will be open from 6:30am until 11:00pm. A call box will be available outside the front of the hotel. Guests can use the call box to access night security staff who can assist with registration or any other issues that may arise when the front desk is not open
We regret any inconvenience this may cause and thank you for your understanding..
The Mammoth Hot Springs Hotel and Cabins—named after nearby springs—offers a warm welcome to summer and winter visitors. The hotel, as it stands today was built in 1936, while retaining a wing of guest rooms originally built in 1911, and features its signature Map Room containing a large wooden map of the United States constructed of 15 different woods from nine countries. In the evening, relax with a drink in the newly renovated Map Room which features a full bar and enjoy the musical delights of a live pianist or get inspired by meeting a local artist with our Inspired By Yellowstone Artist Series in the gift shop. Guests enjoy a variety of in-park accommodations as well as the chance of spotting elk grazing outside the hotel.
