Within the park's massive boundaries, visitors can find mountains, rivers, lakes, waterfalls and some of the most concentrated geothermal activity in the world. The park has 60% of the world’s geysers, as well as hot springs and mud pots. It is also home to diverse wildlife with the largest concentration of mammals in the Lower 48 states, including grizzly bears, wolves, bison and elk.
