Hayden Valley Geyser Basin

Hayden Valley is not only famous for its great opportunities to spot bison, bears, and wolves, but it's also home of thermal areas, for example around Mud Volcano and around Crater Hills. Both are located along the Grand Loop Road between Yellowstone Lake and the Grand Canyon of the Yellowstone. While the Mud Volcano Area is securely accessible via boardwalks and paved trails, Crater Hills is a less developed backcountry setting and only recommended to hikers with appropriate experience.
