Sleeping Princess Professional Review and Guide
"Rock challenges and thrills will delight the most ardent four-wheeler. There’s a great place to stop for lunch just below the summit. The northeast-side descent includes a functioning windmill, ruins of an old homestead complete with a hard-to-find waterfall, and the Wayfarer’s Inn. Watch carefully for bighorn sheep. If you stack rocks to get over obstacles, make sure to remove them when you are done. This is a nasty, dangerous trail that should be driven with at least two other vehicles.
Besides an array of challenging rock obstacles, the road climbs over 2,000 feet through the heart of the Black Mountains. Much of the road is loose, steep gravel. One spot, along the edge of a narrow shelf, requires a sharp inside turn. As your vehicle rounds the bend, your rear outside tire drops into a gravelly low spot. Power must be applied at just the right time to reduce the possibility of going over the edge. Recently a new loop, dubbed the Bob Miller Extension, has been added to the trail. To start the route, you must get around a 15-ft. vertical wall then drop down a very steep embankment. The descent down the northeast side is relatively easy albeit somewhat long and dusty. Stock, high-clearance vehicles can drive up to the top from this side with little difficulty."
