Named after the statesman, John Slidell, this town is a growing suburb of the New Orleans area. Since Hurricane Katrina, Slidell and its surrounding areas have seen a tremendous population surge.
Amtrak, two trains a day pass through. Your other alternative is automobile. Shuttle services that run between the New Orleans airport and hotels on the Mississippi gulf coast may also be available, but you'll have to check availability since Katrina.
You'll pretty much need a car. There are several unreliable cab services in town, the worst of which is Camelia Cab.
