Mammoth Hot Springs is located just inside the Park from the North Entrance. It takes about fifteen minutes to drive there from Gardiner, Montana. Mammoth is unique in that the hot water dissolves limestone under the ground then deposits it on the surface when it evaporates to make these delicate limestone travertine terraces. Really quite beautiful.
Mammoth also has wonderful boardwalks to hike and enjoy the different formations. It is a great way to get out of the car and stretch tired legs.
