Trail Overview
The Senator Highway (FR 52), commonly referred to as the Crown King Road, is a legendary off-road route that climbs from the desert floor near Bumble Bee through Cleator and into the pine forests of Crown King, with a final descent possible into Prescott via various connecting trails. This trail offers a full-spectrum Arizona backcountry experience. Starting from the south, the road begins as a long desert runout--dusty, wide, and relatively mild--passing through old mining towns like Cleator. As you gain elevation and move north toward Crown King, the trail transforms: ruts deepen, rocks get looser and sharper, and water crossings (sometimes up to a foot deep) test clearance and traction. Near the midway point, a notorious rock garden becomes a gatekeeper for those without high-clearance or off-road tires. This level-up section demands good line choice and steady throttle to navigate embedded boulders, loose scree, and ledge climbs. Though not impassable, it separates the casual trail cruiser from the more prepared off-roader. Beyond the hardest sections, the trail weaves through forested hills, continuing to offer steep, eroded climbs and descents, particularly after the town of Crown King, on your way to Prescott. Expect sections of deep ruts, off-camber turns, and exposed shelf roads depending on weather and recent use. Trail Features:Length: ~27 miles from I-17 turnoff to Crown KingWater Crossings: Seasonal, up to 1 footRock Garden: High-clearance and 4x4 required. Traffic: Moderate to heavy on weekends. Towns: Cleator and Crown King both offer small-town stops (food, fuel, beer). Camping: Available along the routeCell Service: Spotty at best, especially beyond CleatorPro Tip: Many choose to ascend from Bumble Bee and return the same way or make it a loop into Prescott via Senator Highway and connect to Walker Road or Poland Junction. The trail is best avoided during or after heavy rains or snow--conditions can deteriorate quickly.
Difficulty
This trail, though well established, is rocky, with random rock gardens and erosion. There are deep ruts in places, as well as shelf-road situations, water crossings that could prove challenging (especially during or after a moisture event) and is mostly one lane wide, with narrow sections to pass. Cell service is intermittent, so offline maps are recommended.
History
The Senator Highway, now known as Crown King Road, is a historic route connecting Prescott, AZ, to the former gold mining town of Crown King. Its origins lie in the early 1860s as part of the Prescott and Lynx Creek Toll Road, eventually extending to the Senator Mine and then, bit by bit, to Crown King. The highway was initially built with private funding and later became a state highway in 1912, connecting Prescott to Phoenix, albeit through difficult terrain. Today, the road is a popular route for recreational off-road vehicles and those seeking a scenic drive through the Bradshaw Mountains. The first section of what would become Senator Highway was constructed in 1866 as part of the Prescott and Lynx Creek Toll Road. The highway was extended to the Senator Mine in 1875, named after the mine itself. The road was gradually extended to Crown King over the following decade. The Senator Highway was incorporated into the state highway system in 1912 and reconstructed. Today, the highway, now known as Crown King Road, is a popular route for off-road enthusiasts and those exploring the Bradshaw Mountains. Crown King itself evolved from a mining town to a tourist attraction, particularly during the 1920s and 1930s. The road passes the Palace Station, a historic stage station, which was a significant part of the history of the area, connecting Prescott to Crown King in Arizona, serving as a gathering point for travelers, miners, and their families. It was built in 1874 and served as a stage stop on the road to the Peck Mine and points south. Today, one can visit the site where the Palace Station stood and observe a cabin on the grounds where this historical building once stood.
