Things to do or see during a lay-over at Atlanta-Hartsfield International airport?

My best advice is to stay inside the airport, because it might take as long to go back through security as you have for a layover. If you go down where the train is to go to a different concourse, if you don't go on the train but use the people walkers downstairs they have some different art exhibits to check out. My other suggestion would be find a restaurant have a drink or something to snack on and then maybe do some shopping. Its not worth leaving the airport during a lay-over. Downtown Atlanta is several miles away from the airport and Hartsfield is the world's busiest airport which includes the fun of going through security again.

you got to have a long layover...bc the atlanta airport is a killer to check into time wise. However, if you got some time, walk downtown peachtree st (aka the strip.) The downtown library is pretty cool too, it's big, if you like to read.

Like the other answer - unless you've got a long layover (more than 3 hours), I would stay put and eat and/or shop at the airport. If you have time to get away and don't want to head downtown on the train - just hop in a cab and have him take you to the new shopping center on Camp Creek Parkway (just a few miles up the road). There's a Barnes & Noble, Target, Clothes stores, restaurants, etc. Have fun.
