Start at the Fall Creek trailhead, empty out at the pit toilet, and head out on the trail to the right of john. Follow it to a 4 way intersection and hang a left. From there, the trail is very well marked. At mile 4.4 there is an option to go right to the Greenline #6 connector. This is merely a shortcut to a point about 1/3 of the way down GL6. If you feel your legs can handle the climb, continue on.
Follow the signs for Wedekind Trail until you reach a road at around 6.3 miles and 1850'. From there, you have several options - continue across the road and to the right to Crestline Trail, go straight across the road to Porter Trail, or turn back around and head back to the car.
