Bison, bears, coyotes, wolves, and birds of prey all call Hayden Valley home almost year-round. Once part of Yellowstone Lake, the broad valley now features peaceful meadows, rolling hills, and the placid Yellowstone River. There are multiple turnouts and picnic areas on the 16-mi drive, many with views of the river and valley. Ask a ranger about "Grizzly Overlook," an unofficial site where wildlife watchers, including NPS rangers with spotting scopes for the public to
use, congregate in the summer. It has 11 turnouts north of Mud Volcano—there's no sign, so look for the timber railings.
