Observation Peak is located in northwest Wyoming's Washburn Range. Built from an ancient caldera rim, the Washburn Range is one of the oldest ranges in the central rockies. The peak is located within Yellowstone National Park, in close proximity to the park's Canyon Village area, famous for the Grand Canyon of the Yellowstone which contains the Upper (109 feet) and Lower (308 feet) Falls of the Yellowstone River.

Observation Peak can be climbed as a day hike, but also makes for an easy and enjoyable overnight backpacking trip. From the summit are excellent views of the Central Plateau area, Hayden Valley, and Grebe Lake.

    Getting There

    Yellowstone National Park occupies the northwest corner of Wyoming, as well as small portions of southern Montana and eastern Idaho. There are five major roads entering the park:
  • West Entrance - Highway 20 through West Yellowstone, MT
  • North Entrance - Highway 89 through Gardiner, MT
  • Northeast Entrance - Highway 212 through Cooke City, MT
  • East Entrance - Highway 20 through Cody, WY
  • South Entrance - Highway 89 through Grand Teton NP
  • The North entrance at Gardiner Montana is the only entrance which remains open during the winter. Refer to the Operating Hours & Seasons page for complete details on road opening and closing dates in the park.

    Additional information can be found on the Yellowstone Plan Your Visit web page.

    Observation Peak and the approach trailheads are located near Canyon Village, in the central region of the park. The peak is most commonly climbed via the Cascade Lake Trail. Refer to the Cascade Lake route for complete details on ascending the peak by this route.

    An alternative route is via Grebe Lake, which is located approximately 2 miles to the west of Cascade Lake. Although longer than the Cascade Lake approach, this is also a scenic alternative with several nice backcountry camping options at the beautiful Grebe Lake. Both routes converge to the same trail for the final 2.5 miles to the summit.
