Getting Oriented
The Bradshaw Mountains lie south of Prescott and west of I-17 in central Arizona, on Prescott NF's Bradshaw Ranger District. The network's main entries are Senator Highway / FR 52 (south from Prescott), Crown King Road / FR 259 (west from I-17 at Bumble Bee), and the Wagoner-Yarnell roads (east from US-89). Crown King at 5,800 feet anchors the interior; Horsethief Basin Recreation Area lies six miles southeast.
What to Expect
The network exceeds 120 miles of designated routes. Most are graded forest roads; named technical trails branch off them. Senator Highway / FR 52 is the main spine, with Castle Hot Springs Road and Crown King Road as the cross-axes. Hard trails include the Algonquin Trail (a steep climb out of Bumble Bee), Gladiator Mine (rocky climb to a mining-era site), and the Castle Hot Springs descent (one-lane shelf road). The system's character is loose volcanic rock, narrow shelf sections, and exposure rather than granite slab.

Where to Camp
Horsethief Basin Recreation Area (USFS-developed campgrounds, lake, and lookout) is the network's interior camping hub. Lower Wolf Creek and Hilltop Campgrounds (USFS-developed) sit on Senator Highway's northern segment. Dispersed camping is allowed on Prescott NF land off the main routes with the standard 14-day stay limit, and the network has many turnouts that work as primitive sites. Crown King has a private campground at the south end of town.
Tips for a Safe and Enjoyable Trip
- Pick up Prescott NF's Motor Vehicle Use Map (MVUM) before riding. Prescott NF has implemented Travel Management strictly; off-route use is enforced.
- Plan around the season. Snow closes the southern segments in January and February; summer monsoons wash out crossings in July and August.
- Carry recovery gear and a spare. The volcanic rock punctures sidewalls regularly.
- No fuel inside the network. Top off in Prescott, Mayer, or Yarnell.
- The Bradshaw Ranger District (928-443-8000) handles current conditions.
- Pair Senator Highway and Crown King Road for a 65-mile loop that returns via I-17.
