35+ miles of old logging roads and very technical singletrack. Great views from an overlook on top of Pine Log Mountain. Killer climbs to the top with hike-a-bikes at times. Plenty of options for creating loops but you'll probably want to bring a GPS or a guide who's familiar with the area.
From I-75, take exit 293 north on HWY 411. Make a left on Stamp Creek Rd (~3 miles). You will see signs for the Pine Log WMA at the intersection. Continue along Stamp Creek Rd until you see the check in station on your left and park in the parking lot.
