Pine Valley Mountains Wilderness Area Trail Professional Review and Guide
"The Pine Valley Mountains are located in the extreme southwestern corner of Utah, on the geologic boundary of the Colorado Plateau and the Great Basin. Like most other ranges in the Great Basin they are very dry and contain no significant lakes. They do, however, contain a number of small creeks and meadows which, at least during the early weeks of summer, are extremely scenic.
Unfortunately, most of the water disappears soon after the winter snow has melted. The best time to attempt this hike is during the month of June, when the meadows are usually green and full of water. As midsummer approaches they soon dry up and the hike becomes much less appealing. Although this hike is only 15.7 miles long there is a great deal of up-and-down along the way, and many people prefer to spend a second night along the trail. If you elect to do this you will have no trouble finding good campsites all along the Summit Trail between Whipple Valley and Nay Canyon. You can camp near water at Whipple Valley, South Valley, Hop Canyon, Hidden Valley or Nay Canyon."
