1. Mardi Gras New Orleans | New Orleans, LA
The largest and most famous Mardi Gras celebration in the USA is in New Orleans, where Fat Tuesday is a legal holiday. NOLA has been celebrating Mardi Gras since the early 18th century and the krewe Twelfth Night Revelers were the first to toss "throws'' in 1870. Beginning on Twelfth Night and ending on Fat Tuesday, dozens of parades are held, including the Chewbacchus sci-fi foot parade in the historic Marigny neighborhood, the Legion of Mars, a salute to military, veterans, and first responders along St. Charles Avenue, Barkus, a costumed canine parade in the French Quarter, the Knights of Babylon with classic flambeaux lighting (gaslight torches) and antique float designs, and the Krewe of Hermes, the oldest nighttime parade. Don't miss two of the most famous krewes: Zulu, famed for its costumes and hand-decorated coconut throws, and Rex, the 153-year-old krewe that parades on Fat Tuesday down St. Charles Avenue. Mardi Gras New Orleans runs through March 4, 2025.
