Mount Holmes Above Early Morning Mist


Located in the northwest region of Yellowstone National Park, Mount Holmes anchors the southern end of Wyoming and Montana's Gallatin Range. With an elevation of 10,336 ft., Mount Holmes is the third highest peak in the range, trailing 10,969 ft. Electric Peak and 10,444 ft. Joseph Peak, both of which are located approximately 12-13 miles to the north.

The hike to the summit of Mount Holmes is ±19 miles (round-trip), with an elevation gain of ±3,000 feet. While strong hikers can make the climb as a long day hike, a more realistic itinerary would be to make the climb as part of a 2 or 3 day backpacking trip.

On the summit is a small stone/wood shelter which serves as one of three primary fire lookouts located within Yellowstone. During the summer months the lookout is manned by a park employee, who may invite you in to chat upon your arrival to the summit. The ranger manning the lookout when we summited also kept a log book for visitors to sign. Based on this log book, somewhere in the neighborhood of 150 hikers visit the summit during an average year.

Mount Holmes was officially named in 1878 by members of the Hayden Survey, after artist and geologist William Henry Holmes of the US Geological Survey. Previous to this the peak had been known as Mount Gallatin, and also for a brief time as Mount Madison.

Views from the summit include the Hebgen Lake area to the west, much of the southern Gallatin Range stretching north to Electric Peak, the Absaroka Range to the east, and large portions of Yellowstone Park to the east and south. On clear days the Teton Range will also be visible to the south.

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

    Mount Holmes is most commonly climbed via the Mount Holmes Trail, which begins from the Norris-Mammoth Hot Springs road in the northwest region of the park. The Grizzly Lake route is a slightly longer variation which includes a visit to the scenic Grizzly Lake. The Trilobite Lake route is an optional spur trail which can be used to ascend or descend the peak. This route must be used in conjunction with one of the other two primary routes. Refer to the individual route descriptions for details on ascending the peak by these routes.
