Natural Attraction

Hayden Valley

Natural Attraction
Hayden Valley overlook along the Yellowstone River in Yellowstone National Park, where a bison wades through shallow water with steam rising from the surrounding marsh.

The wide valley of the Yellowstone River between Canyon and Fishing Bridge is central Yellowstone's great wildlife stage - nearly the entire central bison herd gathers here in July and August.

Planning advice

Best Time To Visit
Dawn and dusk for active wildlife; July and August for the bison rut, when herds and traffic jams both peak.
Tips Advice
  • Use the pullouts - bison jams here are famous, and stopping in the lane is both illegal and dangerous
  • Stay 100 yards from bears, 25 yards from bison
  • Off-trail travel is prohibited July 15 to September 15 in the valley's bear management area; the Mary Mountain Trail itself remains open
  • Pair it with the Grand Canyon of the Yellowstone - the valley starts just south of Canyon Village

Main Features
The Yellowstone River winding through open grassland; roadside overlooks on the Grand Loop between Canyon Village and Fishing Bridge; bison herds and grizzly habitat.
What Youll See
Bison live in Hayden Valley year-round, and nearly all of the central herd gathers here during July and August. The valley is prime grizzly habitat - park biologists have documented high concentrations of bears scavenging bison carcasses.
Unique Characteristics
The most accessible large-mammal viewing in the park's interior - it sits directly on the Grand Loop between two developed areas, so a Canyon-to-Lake drive passes through it.
Safety Considerations
Prime grizzly country - carry bear spray away from your vehicle and respect the seasonal off-trail closure. Bison have injured more visitors than any other animal in the park.
Best Viewpoints
The signed overlooks along the Grand Loop Road, including the Hayden Valley overlook on the Yellowstone River.
Photo Opportunities
Bison crossing the Yellowstone River; steam drifting over the flats at sunrise; grizzlies at long-lens distance in early summer.
Cell Service
None through most of the valley.
Common Wildlife
Bison, grizzly bears, elk, waterfowl along the river.
Best Wildlife Times
Dawn and dusk; July-August for the bison rut.
