10 Best Things to Do in New Orleans

Jackson Square was laid out in 1721 as the Place d'Armes, the military parade ground of the colonial city, and renamed after Andrew Jackson following the Battle of New Orleans in 1815. His equestrian statue stands at the centre of a fenced garden, flanked by the Pontalba Buildings - red-brick rows from 1850 that are among the oldest continuously occupied apartment blocks in the United States.

St Louis Cathedral closes the northern side. The current building dates from 1850 and is the oldest continuously operating Catholic cathedral in the country, with free entry outside services. The Cabildo and the Presbytere on either side house Louisiana State Museum collections covering the Louisiana Purchase and the history of Mardi Gras. Tarot readers, brass players and portrait artists set up along the pedestrian perimeter from late morning.

Three blocks of Frenchmen Street in the Faubourg Marigny hold more live music per square metre than anywhere else in New Orleans. The Spotted Cat, d.b.a., Blue Nile and Snug Harbor run sets from early evening until well past midnight, most with either no cover or a modest door charge, and the crowd skews local in a way that Bourbon Street stopped doing decades ago.

For traditional jazz, Preservation Hall at 726 St Peter Street is the other essential stop. It seats around 100 people on cushions and wooden benches in a bare room with no bar, no amplification and no air conditioning, and runs several 45-minute sets a night. Tickets from USD 25 sell out days ahead, so book online rather than turning up and queueing on the pavement.

The National WWII Museum opened in 2000 as the D-Day Museum and now spreads across six pavilions in the Warehouse District. New Orleans got the museum for a specific reason: Higgins Industries built the LCVP landing craft used at Normandy in factories here, and Eisenhower later credited Andrew Higgins as the man who won the war for the Allies.

Allow four hours minimum. The Road to Berlin and Road to Tokyo galleries each absorb about 90 minutes on their own, and the Beyond All Boundaries film in the Solomon Victory Theater runs a further 45 minutes. General admission sits around USD 32 for adults, with the film and the submarine experience charged separately. Every visitor receives a dog tag that tracks one real service member's story through the galleries.

The Garden District went up from the 1830s, built by wealthy Americans who were not welcome in the Creole French Quarter. The architecture reflects the rivalry - Greek Revival and Italianate mansions on unusually large lots, ringed by cast-iron fences and shaded by live oaks planted a century and a half ago. First Street, Prytania Street and Third Street carry the densest concentration.

Lafayette Cemetery No. 1 at 1400 Washington Avenue holds the above-ground tombs New Orleans is known for, a practical response to a water table that sits barely a metre below the surface. The cemetery has closed for restoration work for long stretches in recent years, so confirm its status before making a special trip. Commander's Palace, serving since 1893, sits directly across the street.

The St Charles line has run since 1835, which makes it the oldest continuously operating street railway in the world. The olive-green Perley Thomas cars date from 1923 and 1924, have varnished wooden seats and no air conditioning, and are a National Historic Landmark in their own right. Windows drop open, which is the whole appeal in summer.

The route covers 13 miles from Canal Street through the Garden District and Uptown to Carrollton, passing Audubon Park, Tulane University, Loyola University and a long parade of antebellum houses. A single ride costs USD 1.25 and a Jazzy Pass gives unlimited travel for USD 3 a day. The full run takes roughly 45 minutes in each direction, and most people ride it as an attraction rather than as transport.

Cafe du Monde has been selling beignets and chicory coffee at the corner of Decatur and St Ann since 1862, and the original stand stays open 24 hours a day except Christmas. The menu runs to four items. Three beignets arrive under an unreasonable quantity of icing sugar for around USD 4, and the cafe au lait is cut with chicory root - a wartime substitute from the 1860s that simply never went away.

The French Market runs from Cafe du Monde down Decatur Street for five blocks, a part-covered arcade of produce stalls, hot sauce vendors, praline sellers and craft stands. It traces its origins to a Choctaw trading post on the same riverbank, which makes it one of the oldest public markets in the country. The flea market section at the Esplanade end is the least polished and the most interesting.

City Park covers 1,300 acres, roughly 50 percent larger than Central Park, and holds the largest surviving stand of mature live oaks in the world. Several of the trees predate the founding of the city, with the McDonogh Oak estimated at close to 800 years old. The Canal Street streetcar runs directly to the southern gate, which makes this one of the easiest escapes from the French Quarter.

The New Orleans Museum of Art anchors that entrance with a collection strong on French, American and West African work. Next to it, the Sydney and Walda Besthoff Sculpture Garden spreads more than 90 pieces across 11 acres of lagoons and oak groves, and entry is free. Storyland, the Botanical Garden and a working 1906 wooden carousel cover the family end of the park.

Mardi Gras World is the working warehouse of Kern Studios, the family firm that has been building carnival floats since 1947 and produces most of the figures that roll in the major parades. The tour takes you across the sculpting and painting floor while artists are mid-project, past 30-foot papier-mache heads in various states of completion and racks of moulds going back generations.

It is the only dependable way to see Mardi Gras up close outside the two weeks of the season itself. Tours run roughly every half hour, last about an hour, include a slice of king cake and a look at the costume racks, and cost around USD 22 for adults. A free shuttle collects from several points in the French Quarter and the Central Business District.

The swamp begins far closer to New Orleans than most visitors expect. Barataria Preserve in Marrero, about 40 minutes southwest of the French Quarter, protects roughly 26,000 acres of bald cypress swamp, bayou and freshwater marsh, threaded with nine miles of boardwalk and trail that cost nothing to walk. It forms part of Jean Lafitte National Historical Park and Preserve, named after the privateer who used these waterways to run goods past the New Orleans customs house.

Alligators, great blue herons, egrets and the occasional armadillo are routine sightings along the Bayou Coquille and Marsh Overlook trails, which link into a straightforward two-mile out-and-back. Rangers lead free guided walks several times a week from the visitor centre. Commercial airboat operators run from nearby landings if you want to get out on the water rather than above it.
