On opposite sides of the Parkway you'll find the bike only campground and the main Natchez Trace Visitor Center. The campground is free and first come first served. At the campground you'll find picnic tables, fire rings with grills, water (April through October), and pit toilets.
The Visitor Center is open daily from 9:00-4:30, and is a great resource for anyone traveling along the Parkway.
