Bill Schwegman provided these travel directions: Go south on I-24, and exit at the Metropolis exit. Go east on U.S. 45 toward Brookport. Just before you get to the City limits of Brookport turn Left onto the Unionville Road which is also the road to the Smithland Lock & Dam. Go 6 miles which will take you slightly beyond Unionville and turn right at a road that should have a sign on it that says Kinkaid Mounds.
Take this road for about 4 miles to the mounds. Portions of this road are just a gravel road. The mounds are approximately 37.08 North Latitude, 88.49 West Longitude if you have a GPS.
Travel time: allow 1 ½ hours one way to the site and another 50 minutes for the tour. In other words, allow at least half a day.
NOTE: This is a primitive site and not really handicap accessible. However porta potties will be available.
