Green River Lakes to Summit Lake Via Highline Trail is a 35.9 mile heavily trafficked out and back trail located near Cora, Wyoming that features a lake and is rated as moderate. The trail is primarily used for hiking, fishing, and fly fishing and is accessible from July until September. Dogs are also able to use this trail.
The first 11.5 miles of trail follows the Green River to Three Forks Park and gains only 350 feet of elevation. From there to summit Lake, the trail is more rigorous, gaining more that 2,000 feet in 4.8 miles
The Hike up this trails is amazing. The view of Squaretop Mountain in the distance near both Green River Lakes and along the beautiful Green River is amazing.I Hiked from the trail-head to the Vista Pass junction this year as part of the Wind River High Route between Green River Lakes and Big Sandy Openings. Hike From Summit Lake to the trail-head on a Big Sandy Openings hike to Green River Lakes year ago.
Hiked down this trail from Summit Lake on the thru-hike in 1990. The river is extraordinarily green and can see why its called the Green River.
Hiked this with my 11-year-old son in early June. The trail was well maintained and mostly clear, although with some deadfalls along the way. Clear Creek was over its banks through the marshy part about 2 miles in (just past the Clear Creek Trail junction) and required an off-trail diversion to cross a side channel over a fallen log. We only hiked about 3 1/2 miles in and camped on the north shore of Upper Green River Lake. Absolutely beautiful country and minimal traffic on the trail. Nightfall found us completely alone to enjoy the sunset on Squaretop Mountain. Looking forward to returning next year and pushing further up the valley.
