Ocmulgee Mounds National Historical Park - Macon

Steve’s take

Twelve-thousand years of human history at one site — the Ocmulgee Mounds near Macon have been continuously occupied longer than almost anywhere in North America. The Great Temple Mound is fifty-five feet tall and you can climb it. The earth lodge is a reconstructed ceremonial chamber that's a thousand years old. Free admission. If you're on I-16 between Macon and Savannah, or passing through Macon on I-75, this is worth thirty minutes of your time. Your kids climb a mound and accidentally learn something.
