Bunker Hill is an unremarkable summit that can be reached, cautiously, with a 4WD vehicle. After you leave the highway, the way up has a number of branch points; GPS or a map will be handy. When you get to the yellow gate, take down your antennas and be carefree about your paint getting scratched, otherwise, park here and hike up. It is roughly a 300' climb over half a mile.
Here is a gaiagps map with driving and hiking information: W7O/NC-038 route.
