It's best to travel around Savannah on foot or bike to truly explore the city's charm. If necessary, taxis or Uber/Lyft may be used for longer distances. Expect to spend around $30-$50 on transportation throughout the trip.
Savannah is a beautiful city with plenty to see and do, but if you have more time, consider taking a trip to the Wormsloe Historic Site or the Coastal Georgia Botanical Gardens. If you have less time, consider skipping Tybee Island and spending an extra day exploring the city's eateries and bars.
The Savannah/Hilton Head International Airport (SAV) is located about 30 minutes northwest of the city center. It serves many domestic carriers, as well as a few international ones. Another option is the Charleston International Airport (CHS), which is about 2 hours away from Savannah by car.
