St. Charles Streetcar
It's formally known as Route 12, but the St. Charles Streetcar is the oldest continually operating streetcar line in the world, having trundled up and down one of the city's main streets since 1835. The downtown stop is in the Central Business District, and it runs uptown in the neutral ground (the median strip) for a distance of some 13 miles. It's an inexpensive way to travel and as a bonus, it provides visitors with a scenic tour of some of the most elegant houses in New Orleans as it passes through the Garden District. When you reach the end, you can get a drink at one of the cafes and head back downtown, looking at the views on the other side of the street.
