Mounds State Park, located off I-69 east of Anderson, features 10 unique "earthworks" built by a group of prehistoric Indians known as the Adena-Hopewell people. The largest earthwork, the "Great Mound", is believed to have been constructed around 160 B.C. Archaeological surveys seem to indicate it was used as a gathering place for religious ceremonies. Be sure to include time to visit the new Nature Center. The new building includes a bird viewing room, small animal displays and much more.
We went on this trail with our 7-year-old daughter. It's easy to walk, but some areas were slightly flooded because of the rain. Mosquitos were out in full force, and we were glad for repellent! The trail is notably wide (we could walk three-across) and not all that isolated (we could hear campers and see residential backyards at several points). However, the bluffs overlooking the White River were more isolated, and the views were rewarding. There are several wooden benches strategically placed along the way.
