Proceed to the southeast side of Pete's Hole Reservoir. You'll find the trailhead just beyond a picnic table. Prepare for 6.8 miles of delightful singletrack, well worth running if you're in the area (Price, Ephraim, or I-70 between Salina and Green River). Getting to the trailhead can be a challenge if not in a high-clearanace four-wheel drive vehicle. But a two-wheel drive SUV should be able to make it okay.
This trail is part of the Great Western Trail (Utah Section) and is signed accordingly, with markers resembling those for the Pacific Crest Trail (See expeditionutah.com/featured…
). It has the high-elevation feel of some of the trails around Gunnison and Crested Butte.
Overall this is a fairly easy run. The first couple of miles are mostly smooth and mostly descend. About a third of the way in there are a few roots and rocky sections, though nothing challenging, and a short moderate climb. There are a few partly overgrown segments.
In about four miles, near Josephite Point, the trail turns south. At this point the trail may become hard to follow, so look for the Great Western Trail marker posts to guide you. The trail shows evidence of being used for horses or packstock in this area; it's heavily divoted in places.
There's a short moderate final climb that takes one to Mary's Lake. When you reach the Mary's Lake trailhead, it's about 500 feet to the lake itself. Beware of mosquitoes at the otherwise pleasant lake.
