Forest Service Road 764 provides access to the Grapevine primitive campsite, a first-come, first-served camping area located off Chattooga Ridge Road approximately 1. 5 miles south of Whetstone Road.

The site offers basic restroom facilities but no potable water, making it suitable for car camping with a 14-day stay limit and no fees required. This access point serves as a gateway to the surrounding Sumter National Forest recreation area near Long Branch.
