Electric Peak is the most prominent peak in the northwest corner of Yellowstone National Park. While very strong hikers can climb Electric Peak as a long day hike, the majority of hikers will want to make the climb as part of a 2 or 3 day backpacking trip, with a camp in the vicinity of the peak.
This trail has everything from fields of wildflowers to views of the surrounding peaks and lots of wildlife. The 20.6-mile trek takes you up the valley and through the forest (along with some creek crossings) up to the base of Electric Peak and eventually to the summit. At the summit of Electric Peak you’ll be able to enjoy unobstructed views across Yellowstone National Park on a clear day.
The route begins on the south side of Kingman Pass at Glen Creek Trailhead and starts through the sagebrush grasslands. Keep your eyes open for wildlife in the plains, mostly mule deer, but some bears and bison have been seen here.
Pass a few trail junctions and follow the signs toward the valley pointed directly for Electric Peak. Past the fields, the trail continues up a river valley for a couple miles and then enters a thick forest. At mile 6, continue straight at a 3-way junction (both across the river/creek at this point) to spend the night at campsite 1G3 or 1G4. The campsites are immediately adjacent to the creek.
On the next day, backtrack to the 3-way junction and turn left to take the trail that leads up to Electric Peak summit. Near the summit, you’ll need to traverse some loose scree. After 10.3 miles, the route ends at Electric Peak. Once at the summit you’ll enjoy some of the best views of Yellowstone Park and can see the Grand Tetons in the distance. Follow the same route back to the trailhead.
