Some sections of the Trail of Tears are preserved as trails today in places like Village Creek State Park and the Trail of Tears park at UALR (which is part of the Coleman Creek Greenway). The Tsa La Gi trail in Fayetteville follows the approximate route of the trail as well. The Fort Smith National Historic site was part of the water route and has exhibits and information on the routes. Visiting any of these locations is a great way to learn some history while you walk, hike, or bike. The Trail also has lots of potential to be expanded and doing so would benefit the public in multiple ways.
I'm sure I'm missing some other sections as well, so let me know about it in the comments below.
