Why hike it

Cap Rock Nature Trail is a short, mostly flat circuit through Joshua trees, Mojave yuccas and sculpted monzogranite formations. Interpretive signs explain local plants and wildlife, while benches provide places to rest.

Cap Rock itself is a popular rock formation in the park’s central area. The trail’s easy access, minimal elevation change and nearby picnic facilities make it suitable for a brief stop.

Getting to the trailhead

The trail begins and ends near Cap Rock, close to the northern end of Keys View Road. From Park Boulevard, turn onto Keys View Road and continue .2 miles to the trailhead.

Parking accommodates cars, buses and RVs. The lot has 2 standard accessible spaces and 25 other spaces. The trailhead area also has picnic tables, grills, recycling, trash receptacles and a scenic photo spot.

Joshua Tree Visitor Center is about 13 miles away. The gateway communities are Twentynine Palms, about 12 miles away; Joshua Tree, about 13 miles away; and Yucca Valley, about 17 miles away. These are straight-line distances, not driving distances.

Palm Springs International Airport (PSP) and Ontario International Airport (ONT) are airports associated with access to the park.

On the trail

The loop starts at about 4,270 feet and returns at about 4,270 feet. Its estimated high point is about 4,310 feet. The route has about 30 feet of total climbing and about 30 feet of descent.

The NPS also describes the trail as having 20 feet of elevation gain. Both figures reflect a route with little elevation change. Most of the trail is flat, with occasional mild inclines.

The native surface consists of dirt and gravel, with hard-packed sand along the route. Weather can leave the sand loose and deeper in some sections. Large overhanging boulders create possible barriers in several places.

Cap Rock is at the beginning of the mapped route. From there, the loop winds among other rock formations before returning to its starting point. Benches and interpretive signs appear along the way.

What you will see

The central feature is Cap Rock, a distinctive and popular formation near Park Boulevard and Keys View Road. The walk continues through nearby granite and monzogranite formations.

Joshua trees and Mojave yuccas grow beside the route. Signs provide information about the area’s plants and wildlife. The trailhead and Cap Rock area also serve as a designated scenic viewpoint and photography spot.

Shade is minimal throughout the loop. There is no cell service at the trail.

History and nature

Cap Rock Nature Trail is designed as an interpretive walk through the surrounding desert landscape. Its signs describe plants and wildlife found in the area.

The route also highlights the relationship between local vegetation and sculpted monzogranite. Cap Rock and the surrounding formations are the trail’s defining geological features.
