Mostly unpaved, the 20-mile Cedar Canyon Road connects Kelso Cima Road in the west with Ivanpah Road in the east, paralleling (and sometimes joining) the historic Mojave Road. Black Canyon Road (unpaved north of Hole-in-the-Wall) connects Cedar Canyon Road with Essex Road, 20 miles to the south.

Rock Springs
Wayside exhibits, no services.

A well-known watering hole for early travelers, Rock Springs is located 5.2 miles east of Black Canyon Road on Cedar Canyon Road, then 0.25 miles south on a sandy, unmarked road (four-wheel drive recommended). Camp Rock Springs, a military redoubt established in 1866 to protect travelers and mail, was one of the most isolated and comfortless army posts in the West.

Mid Hills
Campground, trailhead, vault toilets, water. Not recommended for RVs.

About 2 miles west of Black Canyon Road at the north end of Wild Horse Canyon Road, Mid Hills supports pinyon-juniper woodland habitat. The effects of a fire that swept through the area in June 2005 are still evident, although several campsites in the popular campground still contain shady stands of pinyon pine and juniper.

Hole-in-the-Wall
Information center, bookstore, campgrounds, picnic area, trailhead, restroom, water, telephone.

Just north of the junction of Black Canyon and the south end of Wild Horse Canyon Roads, rhyolite cliffs riddled with holes and hollows are the backdrop for Hole-in-the-Wall.
