Drive 6.5 miles (10.4 kilometers) down this road to access the 2.2 mile round-trip Grapevine Hills Trail to Balanced Rock. Geologically, Grapevine Hills is a laccolith - a mushroom-shaped igneous intrusion that domed the rocks above, and was later exposed by erosion. The road is very rough and requires a sturdy, High Clearance vehicle. Do NOT attempt to reach the trailhead with a passenger car, minivan, or RV. 

Driving the road beyond the trailhead usually requires 4x4. Five backcountry campsites are located at different places along the road. A backcountry permit is required to stay at these campsites. Permits are reserved by going to www.recreation.gov.
