In the early days, Yellowstone’s visitors began their park exploration at Mammoth Hot Springs, named after the steaming limestone terraces just above the hotel area. Today, Mammoth Hot Springs Hotel offers a warm welcome to summer and winter visitors. Elk routinely graze outside the hotel around the parade grounds of what was once Fort Yellowstone. Televisions, radios, air conditioning, and Internet service are not available. Wheelchair accessible accommodations are available on a limited basis. Mammoth Hot Springs Hotel is open in the summer and for the winter.
