Bunsen Peak Trail (U.S. National Park Service)

View of a valley covered in sagebrush-steppe from a tan, rocky trail near the top of a mountain.

Climb 1,300 feet through forest and meadow to the summit of Bunsen Peak, named for German chemist Robert Bunsen who studied geysers and invented the Bunsen Burner. The summit offers panoramic views of the Blacktail Deer Plateau, Swan Lake Flat, Gallatin Mountain Range, and the Yellowstone River Valley. Return by the same route.

Safety notes: Grizzly bears frequent this area. You’ll also see communications equipment, which supplies Mammoth and nearby communities.

Trailhead: 5 miles (8 km) south of Mammoth on the Grand Loop Road. Park in the gravel lot just south of Golden Gate, across from the Glen Creek trailhead.

This is a 4.6-mile (7.4-kilometer) there-and-back trail that begins and ends at the same trailhead.

Moderately strenuous
