Plan a trip to Columbus
Located smack-dab in the middle of the state, Columbus is Ohio’s state capital and most populous city. With a diverse economy spanning from aviation to education, technology and cutting-edge medical research, Columbus is rapidly becoming one of the most livable cities in the Midwest. Columbus straddles the Scioto River with an integrated system of riverfront parks and paths stretching along the waterfront, now known as the Scioto Mile. Visit COSI, a sprawling hands-on science museum with exhibits for all ages. Tour the Ohio Statehouse or the Columbus Museum of Art, which features a creative hub for visitors to share ideas and make art themselves. German Village is the neighborhood to sample the city’s best Bavarian fare, while hockey fans flock the Arena District to see the Columbus Blue Jackets skate on home ice.
