New Orleans cemeteries pose several real risks that range from physical injury to heat-related illness, which is why some have restricted public access or closed entirely for renovations. The dangers aren’t dramatic or mysterious. They’re practical: uneven ground, crumbling structures, extreme heat, mosquitoes, and occasional crime.
Unstable Structures and Uneven Ground
New Orleans buries its dead above ground in stone and brick tombs, many of which are centuries old. Over time, plaster cracks, bricks loosen, and entire walls can collapse into piles of rubble. Tree roots push through walkways and into tomb foundations, creating buckled paths that are easy to trip on. The combination of crumbling pathways, shifting earth, and deteriorating tombs makes falls one of the most common hazards for visitors.
Lafayette Cemetery No. 1 in the Garden District was declared an unsafe environment for general visitation by the city of New Orleans, largely because of these structural problems. Magnolia and oak tree root systems had damaged both tombs and walkways so extensively that the city brought in arborists and other professionals to assess the situation. Repair work included removing accumulated mud and leaves from paths, cutting back branches overhanging walls and tombs, and addressing root damage throughout the grounds. The cemetery’s planned reopening in spring 2020 was further delayed by the pandemic.
Extreme Heat and Humidity
Most visitors tour New Orleans cemeteries on foot, with little to no shade depending on the cemetery. In a city where the heat index regularly tops 100 degrees, spending 60 to 90 minutes walking on sun-baked stone paths is a real health concern. The above-ground tombs absorb and radiate heat, and the enclosed layout of many cemeteries limits airflow.
Dehydration sneaks up fast in these conditions. By the time you feel thirsty, you’re already behind on fluids. Licensed tour operators reserve the right to cancel tours during extreme heat, and for good reason. If you’re visiting during summer months, drinking water before you arrive (not just during the tour) makes a significant difference. Morning hours are the safest window for a visit.
Mosquitoes and Standing Water
Cemeteries collect standing water in flower vases, on flat tomb surfaces, and in low spots where drainage is poor. In New Orleans’ subtropical climate, that stagnant water becomes a breeding ground for mosquitoes. During the Zika virus concerns of 2016, the city’s mosquito control office worked directly with cemetery directors to address the problem, asking families to keep vases free of standing water. But the issue is ongoing. Visitors regularly report being swarmed, particularly during warmer months. Mosquito-borne illnesses like West Nile virus remain a background risk in the region, so insect repellent is worth packing.
Vandalism and Crime
Years of neglect, vandalism, and theft have taken a toll on New Orleans cemeteries. Visitors have broken bricks off unrestored tombs, scratched markings into plaster, and in some cases, unlicensed tour guides have reportedly removed bones and photographed exposed remains inside tombs. These aren’t just preservation concerns. Damaged tombs with exposed interiors and loose debris create additional physical hazards for anyone walking nearby.
Crime against visitors has also been a factor. St. Louis Cemetery No. 1, the city’s oldest and most famous, moved to a guided-tour-only model in part because of safety concerns about unaccompanied visitors in a relatively isolated, maze-like environment. The narrow rows between tombs limit sightlines, and the cemeteries are often located in neighborhoods where opportunistic theft can occur.
How Guided Tours Reduce Risk
Several of the most visited cemeteries now require or strongly encourage guided tours. Groups are typically capped at around 20 people, and guides know the safest paths through the grounds. They also monitor weather conditions and will cancel for lightning, hail, or dangerous heat. Comfortable, closed-toe shoes with good grip are the single most important thing to wear, given the uneven surfaces throughout these sites.
The Catholic Cemeteries of New Orleans prohibit bike tours and motorized vehicles inside their grounds, ban food and alcohol, and ask visitors not to touch the fragile plaster and brickwork on tombs. These rules exist because the structures genuinely cannot withstand casual contact. A light push on a deteriorating wall can bring down material that has been holding together by little more than gravity and habit for over a hundred years.
Why the Risks Persist
The core problem is that New Orleans sits at or below sea level in a hot, wet climate, and its cemeteries contain structures built as far back as the 1700s. Water seeps into brick and morite, freeze-thaw cycles (rare but not unheard of) crack plaster, and subtropical vegetation grows aggressively into every gap. Maintaining hundreds of family-owned tombs across dozens of cemeteries requires coordination between the city, the Catholic archdiocese, and individual families, many of whom no longer live in the area or have the resources for upkeep. Without consistent care, as preservationists have noted, a historic tomb can deteriorate into nothing more than a pile of rubble. The dangers visitors face are ultimately the result of age, climate, and the enormous challenge of preserving an outdoor museum that was never designed to be one.
