White Rock Spring Trail #39

Trail Description: Like many of the trails in this area, White Rock Spring Trail #39 was originally a road built in the late 1800s to provide horseback access to springs and other cattle waters. The trail passes through mixed chaparral as it traverses an open, exposed landscape between Blair Pass and its junction with Upper Pasture Trail #38. From its highest terrain, there are expansive views of the ranch lands of Skull Valley, and beyond that, distant mountains. Watch for scrub jays hopping through the brush and hummingbirds somersaulting through the air like tiny bejeweled acrobats. Also keep an eye out for the snakes and lizards that sometimes bask on sun-kissed granite along the trail. For a pleasant loop hike, take Trail #39 to Upper Pasture Trail #38. Travel east on Trail #38 to its junction with Little Granite Mountain Trail #37. Take Trail #37 north to Blair Pass and the beginning of Trail #39. This loop is approximately 4.5 miles long, not including travel on Granite Mountain Trail #261 (used to access Trail #39).


Notice: Visitors are asked to be alert and stay on existing trails when recreating on Granite Mountain as the area recovers from the Doce Fire of 2013. Soil erosion has occurred on portions of the trails, thus exposing more rock, and cross-country travel increases the possibility of encountering rolling rocks, stump and root holes, falling trees, and loose soils from rains.
