Travel approximately 6.4 miles down the Grapevine Hills Road to access the Grapevine Hills trailhead. Here, a 2.2 mile roundtrip desert trail leads to the picturesque Balanced Rock, the highlight along this road. This is a great morning or evening hike, but can be very hot mid-day. Geologically, Grapevine Hill is a laccolith, a mushroom-shaped igneous intrusion that domed the rocks above, and was later exposed by erosion. Grapevine Hills Road is generally accessible to all vehicles, and begins 3.3 miles west of Panther Junction along the north side of the road. After reaching the Grapevine Hills trailhead, the road may become rough and require high-clearance, especially after any rainfall.
