Crestline starts with a steep, loose climb. That section eventually mellows out into some fun trail. The trail crosses roads often and is easily picked up on the other side of the road until you arrive at a 4-way intersection around mile eight. In front of there will be three roads. Choose the center road, follow it for no further than a football field and look to your left.
From here, Crestline Trail heads up and into the woods again. There are two short, very steep, heart thumping hills followed by some extra downhill that will lead you into a short rocky section and back onto the road at the top of Greenline #6
