I remember New Orleans was the first place I ever tried alligator meat as a kid. I'm sure the kids would enjoy beignets at Café du Monde
. Also maybe look for a place with Bananas Fosters. Get some crawfish and gumbo for the kids too.
Ride the streetcar trolleys as Rosalie mentioned, that's fun to do. You could go see real gators on a swamp tour. Check out jazz at Preservation Hall
which should be all ages.
Go to City Park
and check out StoryLand
. There is also the Louisiana Children's Museum
If you happen to be driving to New Orleans, I remember being amazed as a kid by the Lake Pontchartrain Causeway
, the longest continuous bridge over water in the world.
