Start at Glenwild and go up Stealth. After turning onto Flying Dog, you stay on Flying Dog for a clockwise loop. (You pass both ends of the Preserve Connector, but don't ride on it.) After descending the lower switchbacks of Flying Dog, you hit either side of the Cobblestone Loop then drop toward Glenwild. When you reach Glenwild, you go left and ride the easier half of the loop back to the trailhead.
At the I-80 Park City (Kimball Junction) exit, go north (left from the exit if you're coming from SLC) to the frontage road. Turn right. About 1/4 mile later at the second road on your left, turn left. Find the trail parking area just before the northbound road crosses the creek.
