Wolverton Mountain Trail 9415 starts just across Hwy 89 from White Spar Campground on White Spar Road just south of Prescott. From the start it is climb, climb, climb.

The trail starts in the trees with nice flowing easy climbing. Then after a short downhill, grab your lungs and be ready.

As you climb out of the trees look off to the right and you’ll see great views of Prescott from Thumb Butte in the west to the Dells farther to the east.

More climbing is ahead as you wind your way higher and higher. At about 4.2 miles you’ll come to a gate.

Pass around the gate and on to the doubletrack. A bit more climbing and then finally some downhill to the intersection of Trail 48.

Wolverton Mountain Trail. This lovely, pine-chaparral trail is also dubbed the Sierra Prieta Trail, forest trail #9415 and is now also part of the City of Prescott Circle Trail System.

Anchored by two easy-to-access trailheads, we begin the hike at the Aspen Creek lot on Copper Basin Road. From here, the trek begins across the road on trail #48 (Aspen Creek Trail).

Go steeply uphill 0.4 mile to the turn off for “9415” (Wolverton Mountain Trail) at the second junction. Note that the “9415” signs are located a few yards past the intersections—so make sure you locate them before making any turns.

Along the way, two side trips make for interesting exploration.

First up–just past the a gate near mile 1.2–there’s a short 0.5 mile dirt road heading left that leads to a weather station below a high ridge on Wolverton Mountain where nice views of Prescott’s Thumb Butte area shine below.

The second detour is a highly-recommended trip up to White Spar Peak (a.k.a. Quartz Mountain). At roughly 2.5 miles, turn right onto trail 9415A and follow a maze of old roads to a point just below the top of the snowy-white quartz massif. Here, it’s easy to pick out informal paths that lead to the summit.
