Augusta is a drivable city, and it is recommended to rent a car if you do not have one. Public transportation is not always the easiest way to get around, especially if you are on a tight schedule. Driving will give you the freedom to explore at your own pace. Uber and Lyft are available in the city and could be a good option if you don't want to navigate the city yourself. Expect to spend around $35 to rent a car for the day, and around $20 for an Uber/Lyft ride from the airport to the city center.
If you have more time, consider visiting The Riverwalk, Phinizy Swamp Nature Park or golf at Augusta National Golf Club, one of the most prestigious golf courses in the world. With less time, consider skipping the Augusta Museum of History or cutting your time at Whiskey Bar Kitchen short.
The Augusta Regional Airport, (AGS), is about 20 minutes from downtown Augusta. The airport is small but has flights available through several major airlines, including American, Delta, and United.
