What is the number one, must-see attraction in the state of Louisiana? Any guesses?

Have you ever thought about just how big the United States is? I once heard an interview with a band on their first U.S. tour. They said they realized how big this country is when they traveled from one side in shorts and flip-flops to the other side where they quickly needed to change into long pants and coats. And which such a large piece of land, comes many sights to see.

Ah, tourism.

It's easy to say that each state has something unique to offer, but what is the best of the best? PopSugar.com set out to answer this with their list, "50 States of Unbelievable Tourist Attractions." If you had family or friends passing through, what would you tell them that they have to see?

Steamboat Natchez

This staple in New Orleans is what PopSugar picked as the top tourist attraction in Louisiana. Some couples even elect to get married aboard this vessel. Steamboat Natchez is so popular that they are launching a sister vessel called Riverboat City of New Orleans with a plan to host Mardi Gras Jazz cruises.
