Start at the trailhead located across the street from the Visitor Center and the remains of the old Sugar Mill (the trail's namesake). Continue to follow the gravel path through the woods enjoying the local flora and fauna. This trail serves as the feeder to access both the Fountainbleau Hiking Trail Loop and the Alligator Marsh Boardwalk. The trail dumps out into an open field. Follow the field out and turn into the double rows of live oaks. Hold that line until you get back to the sugar mill.
