Journey to 52 miles outside of Pinedale to Green River Lakes, lakes carved out by glaciers and replenished each year from the snowmelt of the Wind River Mountains. The lakes are the source for the Green River, major tributary of the vast Colorado River system. Stands of aspen and pine cover the hillside for much of this section if your starting point is Green River Lakes Trailhead, but you will find wet meadows and marshy ponds dominating the landscape at Fish Creek Park near the end of the journey at Union Pass.

At the halfway point in this section of trail in the Gunsight/Roaring Fork area, you are sure to find solitude where you may encounter a coyote or deer or other wildlife sightings but it is rare to meet up with another human. The view of the Tetons from Gunsight Pass is incredible. On a summer adventure, one might discover abundant mountain wildflowers and glimpses of wildlife such as moose, elk, deer, bear, hawks and eagles.

Difficulty: Moderate

Length: 15+ miles one-way (new mileage with reroutes?)

Family Friendly Option: The segment begins at the Green River Lakes Campground so it is easy to enjoy the beauty and recreational opportunities around the Green River Lakes area with birds’ eye views of the much-photographed Squaretop Mountain. Leave the crowds behind as you hike a couple miles of the CDT heading south towards the Bridger Wilderness and along the eastern shores of the Lakes. Keep your eye out for the occasional moose who like to swim in the lakes.

Directions: Green River Lakes TH: Take US Highway 191 west from Pinedale. About six miles from Pinedale, you will reach the Cora turnoff at the junction of State Highway 352. Turn right, towards Cora, and keep going until you reach Green River Lakes. The last 23 miles of the trip is on a rough dirt road maintained by the Forest Service. During the summer it is suitable for most cars, but slow speeds are necessary, so plan a leisurely pace for your trip. Union Pass Road: From Dubois drive 8 miles on US 26/287 to Union Pass Road. Turn left onto gravel road before the DuNoir Gas Station. Follow Union Pass Road for 5.4 miles to the FR 532.
