On foot
The entire corridor of High St US Route 23 from Clintonville in the North to Merion Village in the South is extremely pedestrian-friendly, though it does pass through some less-than-scenic areas, particularly the few blocks between campus and the short north.Downtown Columbus is a walkable city with most attractions located within a 20 minute walk of each other. The Columbus Landmarks Foundation conducts walking tours, too. (http://www.columbuslandma...)
By car
Columbus is a car-centric city, with usage of a car required outside of the areas directly surrounding downtown. Parking is extensive and reasonably priced at almost all major destinations. There are many surface lots and garages around the city. There are only a few areas of the city, like the Short North, where parking can be hard to come by; those locations all feature abundant valet parking at an affordable $5 per vehicle. Keep in mind that U-turns are illegal citywide in Columbus.Downtown is a short ten minute drive $20 taxi fare from Port Columbus the airport via I-670W.
