Old jeep trail. Might as well be single track, as you will have fun picking a line. The most technically demanding ride, I know of in NGA. Gains 2k in elevation before the downhill. Not for the novice or the weak!
From 515m take Rock creek rd to game checkin on left. Park here. To start ride continue up road 1/2 mile to first gated road on right. Ride past gate and stay on main jeep road (Note: there are some other jeep roads that intersect, but they are overgrown / not used as much) Once you reach the top of Rich Mt hold on as there are 5 miles of super technical downhill. Eventualy you will come to a gate, continue on, easier gravel road down past quary. Take 515 N to Rock Creek and back to the beer. On, On
