With more than 500 restaurants, countless shops and quaint attractions like Falls Park, Sioux Falls is a perfect first stop for many I-90 road trips. Heading west, stop in Mitchell, home to the iconic World’s Only Corn Palace, a one-of-a-kind landmark featuring murals made from real corn. Farther west, discover Chamberlain, where Interstate 90 meets the Missouri River. This scenic town offers stunning views and cultural immersion with the Aktá Lakota Museum, which features artwork and artifacts from Indigenous culture. Keep an eye out for the 50-foot-tall statue, Dignity: Of Earth & Sky, which features a Native woman gracefully wearing a quilt featuring 128 stainless steel blue diamond shapes designed to flutter in the wind.
As you continue west, Murdo awaits with its Pioneer Auto Show, featuring over 300 classic cars and a collection of early prairie town buildings that transport visitors back to South Dakota’s pioneer days. A little farther down I-90 is the stunning Badlands National Park, known for its rugged, otherworldly rock formations.
