Starting at the Lucia Falls trailhead inside the Moulton Falls Park, the trail climbs immediately upward from 450 feet to 1600 feet in 1.5 miles. Don't despair, the view at the top is worth the effort. The climb is, however, rather steep and a little grueling. Once you cap out at the top, there are a few lovely spots to take photos and give your legs a break. Then enjoy some nice smooth downhill for the next 1.5 miles.
The next few miles are mostly relaxed and easy singletrack, with only a few a few short climbs.
At mile 4.1 you'll enter a clear cut area. Stay on the trail until you hit a logging road then hang a left and climb up and around a small hairpin corner. At mile 4.5 (ish) you'll see the trail on the left hand side of the road. Dip off the road onto more singletrack goodness. Continue on until you hit the Cold Creek Campground. Take a break before reversing and heading back to Moulton.
