From Pinedale, drive south on Hwy 191. At Boulder, turn left on Hwy 353 and drive 18 miles to the end of the pavement. Shorty after the pavement ends, go straight through the junction, and drive south crossing the Big Sandy River (Buckskin Crossing). At next junction, turn left (east) and drive 7 miles. Turn left at the following jct and follow the main road to the Big Sandy Campground and trailhead. This trailhead is remote, so be sure to have a full tank of gas.
Hiked this at the end of a multi-day trip with a base camp on Big Sandy Lake. Maps didn't show a trail but because of such high use found a trail about 2/3 of the way to the lake coming up the ridge near the river drainage from the lake. Small beautiful lake that is less heavily used than Big Sandy
