The northern trailhead of the Highland Rim Trail section of the Natchez Trace National Scenic Trail is at the Garrison Creek stop on the parkway. Garrison Creek, at milepost 427.6, is located half a mile south of the Leiper's Fork exit and about 15 miles south of the northern terminus of the Trace and Nashville.
The Garrison Creek trailhead is popular for both horseback riders and hikers. There is a large parking area for horse trailers on the north end of the parking lot. Picnic tables and hitching posts are found next to the creek. Drinking water is available at the restroom. Hikers can start their walk from the trailhead near the restrooms, or at the trailhead near the picnic tables.
The Highland Rim trail is roughly 20 miles long ending at the southern terminus located just off TN Highway 50 in the Shady Grove area. The southern trailhead is also a staging area for horseback riders as is the trailhead located off of TN Highway 7. Other access points to the trail for hikers include War of 1812 Memorial/Old Trace, Burns Branch and the Tennessee Valley Divide.
