The Mammoth Hot Springs Hotel and Cabins—named after nearby springs—offers a warm welcome to summer and winter visitors. The hotel recently underwent major renovations of the public spaces and guest rooms. 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 kinds of wood from nine countries. Guests enjoy a variety of in-park accommodations as well as the chance of spotting elk grazing outside the hotel.
