Trail maps for Pine Mountain can sometimes be found at the trailhead on the East side on Grantville Rd.
Hike down the white blazed Billings Trail {Called the Tait Section} until you get near the geocache GC16E3A "Got Wood? Series: Stumped". From there, you will see a trail heading down the hill to a small bridge. Over the river and through the woods, there will be an intersection. Take the East Summit trail loop on the right up to the East summit and cache.
Keep following the trail to complete the loop, or head back and take a right onto the Pine Mountain trail.
