Most first-time visitors prioritize three areas: the Short North Arts District, German Village, and the Columbus Zoo and Aquarium, but the full list depends on how much time you have.
The Short North, running along High Street just north of downtown, is walkable and free to explore. It concentrates galleries, independent restaurants, and bars in about a mile stretch. German Village, roughly a mile south of downtown, is a 233-acre neighborhood of 19th-century brick architecture listed on the National Register of Historic Places. Entry is free; the main draw is wandering Beck Street and stopping at Schiller Park.
COSI (Center of Science and Industry) sits on the west bank of the Scioto River, adjacent to downtown. Adult admission runs around $29.95, children slightly less (confirm current pricing at cosi.org, as rates update periodically).
The Columbus Zoo and Aquarium in Powell, about 20 miles north of downtown, consistently ranks among the top zoos in the country by attendance. General admission is approximately $24–$28 depending on the season.
For a free option, the Columbus Museum of Art on Broad Street offers free admission on Sundays, with weekday adult admission around $18.
The Arena District, immediately northwest of downtown, is worth a visit on Columbus Blue Jackets game nights if your timing lines up. Nationwide Arena seats just over 19,000.
A long weekend covers the downtown core, Short North, and German Village comfortably on foot.
