Perched on the edge of Sheepeater Canyon and Golden Gate Canyon near the Wyoming-Montana border, Bunsen Peak’s 8,564-foot summit reveals sweeping views across the northwest corner of Yellowstone National Park. From the Bunsen Peak Trailhead, turn left at the first trail junction to start the clockwise loop.
The first mile winds east across a sagebrush-dotted landscape to the base of Bunsen Peak. After 1.3 miles, the switchback climb begins up Bunsen’s northwest ridge—look to the north for the first views of Cathedral Rock, a towering rock formation. Crest the summit after 2 miles and stop to savor the views that stretch out in all directions. Electric Peak rises to the northwest, the Absaroka Range to the northeast, and Mount Holmes to the southwest.
From here, the trail zigzags down Bunsen’s northeast ridge toward Sheepeater Canyon. Turn south off the ridgeline near mile 4 to navigate around the base of the peak. The final 3.2 miles of the loop travel southwest through sagebrush grassland back to the trailhead.
