As mentioned, this hike begins about six miles down Grapevine Spring Road, a well-maintained gravel road that begins near the Panther Junction Visitor Center. A 2WD vehicle with lower clearance is usually sufficient, but a higher clearance SUV or truck could make the drive more pleasant. The parking area is small, however, so larger vehicles may wish to consider another hike instead. There's no water or restroom area available at the trailhead.

Following the Balanced Rock Trail (sometimes listed as Grapevine Hills Trail), you will wind through a sandy wash filled with desert scrub with numerous jagged peaks defining the horizon. "The final quarter-mile of the trail is the most challenging and the most fun," according to this source, requiring a "bit of rock scrambling to get up and over the large boulders on the trail." Snakes are common, however, so consider reading this guide of snakes that can be found in the Big Bend Region - including whether they are venomous or not.
