Plummer Canyon

Plummer Canyon is a 10-mile out-and-back hike in Wyoming's Jedediah Smith Wilderness, within the Teton Basin Ranger District of the Caribou-Targhee National Forest. The trail climbs from a low of about 6,600 feet to a high of about 8,400 feet, with a total elevation gain of roughly 2,000 feet. The Forest Service manages the land, and the route is natural-surfaced and open to horses. Summer is the most comfortable time to go. Typical averages from a nearby weather station show July highs around 77°F with lows near 42°F, and snow is common from November through April. That station sits well below the trail, so temperatures on the high point run cooler. The trail is open from June 1 to October 31, and the Moose Creek parking area is the trailhead. The Game Creek and N. Game Creek hikes start about half a mile away, and the Mike Harris campground is about 4 miles off.
