Features -none-


Includes the first half of the IMBA Epic long course. Includes Three bridges trail, Green Shoot, Bald Knob Ridge Trail, Maguire trail, Lower trail, New Laurel Run trail and finishes up on Lonberger trail.
Open year round, but watch for hunting seasons in the fall.


This is a great after work ride, or weekend ride. A normal relaxed ride pace will take you about two hours. Start the ride from the Galbrith forestry lot. Follow Black Gum trail out of the parking lot, then take a right on the road cross over the bridge and take a left onto Galbrith Gap trail. When you pop out on the Laurel Run road you'll see a rock armored trail just ahead and to your left called Lonberger Trail. Go ahead and give it a climb.

When you reach the top, take a right and continue on to three bridges trail. If you need water this is the perfect place to fill up your pack. If you cleared the three bridges and the big rock garden, pat yourself on the back and continue your climb up Laurel Run road. Turn right on to Bald Knob Trail and stay left onto Green Shoot trail. Prepare your self for about 100 yards of rocks. Once you clear them it will be a relatively smooth climb up Green Shoot. Once at the top, take a left on Bald Knob Trail and prepare yourself for a rocky but very rideable ridge trail - speed and big tires are your friend.

Turn left on Maguire Trail and enjoy your smooth flowy ride down to Lower Trail. Turn left onto Lower trail and follow it out to Laurel Run road. Turn right and climb Laurel Run road until it Y's with Little Flat Tower road. Turn Left and climb Little Flat Tower road all the way to the top. Just prior to reaching the fire tower you'll see a sign for New Laurel Run Trail on your right. Turn right and descend on that trail. Now turn left and descend Laurel Run road and then turn left again onto Bear Gap road and settle in for a long climb to the top. When the road levels out on top, turn left on Gettis ridge road and then a left to descend North Bear Meadows road.

Enjoy your view of Bear Meadows on the way down. Now at the bottom, turn left on to Upper Lonberger and continue with some rocks for a bit till you join Lonberger. Lonberger will smooth out as you descend. You should be back where you started. Hope you enjoyed your ride.

Oy - this took me well over 3 hours but I'm in my 50s...lots of fun technical - too much humping. Outstanding trail maintenance & spot-on direction...
