The Chapel is not a designated trailhead and if you are parked there after 5pm, your car will remain there until at least 7am. Park down the hill and ride up if you're starting here. This trail is frequently done as part of a larger loop, so this isn't much of a problem.
Starting from the Chapel, go down a rocky, fairly steep singletrack until you start to contour around the hill on smoother trail. Occasional rock obstacles keep things interesting but never terribly hard all the way to where it ends at the Little Horse Trail.
