The best ways to get around New Orleans are on foot and by public transportation. The city's neighborhoods are very compact, making them perfect for strolling tourists. If you don't feel like walking, hop on one of the famous streetcars. Unless you're planning extensive or remote explorations outside of major tourist areas (and, well, we recommend some peripheral destinations), you don't really need to rent a car during your stay in New Orleans.
The city is flat, very picturesque and made for walking; there are plenty of taxis (including Uber, Lyft and bike taxis) and decent public transport. In fact, a tram ride is both entertainment and a practical way to get around. Meanwhile, driving and parking in the French Quarter can be difficult. Many streets are narrow, bumpy, crowded and one-way.
Outside the square neighborhood, the streets lean in directions that defy logic in an attempt to line up around the curved Mississippi. Street parking is minimal and parking, including hotel parking, is extremely expensive. The best way to get around New Orleans is on foot and by streetcar. Many tourists will spend most of their time in the French Quarter, but if you stroll through City Park to see the New Orleans Museum of Art, you can do it quickly on foot and by streetcar.
