Mammoth Hot Springs Hotel sits at the northwestern corner of Yellowstone National Park, surrounded by cascading white and orange travertine terraces sculpted over millennia by superheated water rich in calcium carbonate. The springs discharge at around 54°C, depositing mineral terraces that shift and evolve year by year. Guests staying at the historic hotel have unrivaled dawn access to the boardwalk trails winding through Upper and Lower Terraces before the crowds arrive.
