Louisiana is home to roughly 2 million wild alligators, and a Bayou Swamp Tours trip departs about 30 minutes from downtown New Orleans to find them. This field guide covers gator size, diet, brumation, and where you will see them across six daily departures starting at 8:00 am.

How Many Alligators Live in Louisiana?
The population is enormous. The Louisiana Department of Wildlife & Fisheries estimates roughly 2 million wild alligators statewide, plus nearly 1 million more raised on alligator farms. That density is why sightings on a warm-weather swamp tour are close to guaranteed.
The species itself is a conservation success story. The U.S. Fish & Wildlife Service declared the American alligator fully recovered and removed it from the endangered species list in 1987, one of the fastest wildlife comebacks on record.
How Big Do American Alligators Get?
Alligators are the largest reptiles you will meet in Louisiana. According to the U.S. Fish & Wildlife Service, adult males commonly reach 11–13 feet, while females rarely exceed 10 feet. Hatchlings start at just 6–8 inches, so a swamp tour often shows a whole size range in a single afternoon.
- Hatchlings: about 6–8 inches long
- Juveniles: 2–6 feet, the most commonly seen
- Adult females: up to about 10 feet
- Adult males: commonly 11–13 feet
What Do Alligators Eat?
Alligators are apex predators with a broad diet that shifts as they grow. Juveniles eat insects, small fish, and crustaceans; adults take fish, turtles, birds, and mammals. They are ambush hunters, lying still for long stretches before a sudden lunge, which is why you often see them motionless near the bank.
Because they are cold-blooded, digestion and appetite depend on temperature — another reason warm months put on the best show.
Why Do Alligators Disappear in Winter?
Cold shuts them down. The Smithsonian's National Zoo explains that alligators become sluggish and stop feeding when water temperatures drop below about 70°F, entering a dormant state called brumation. They dig into mud banks or float with just their snouts exposed, so winter sightings are rare.
This is why the season shapes your trip. For a full month-by-month breakdown, read our guide to the best season for swamp tours.
Where Will You See Them on a Tour?
You will see alligators in the protected wetlands ringing New Orleans. The Louisiana Department of Wildlife & Fisheries notes the Honey Island Swamp area covers nearly 70,000 acres of cypress channels and marsh — prime gator habitat. Captains cut the engine near sunny banks and quiet backwaters where the reptiles gather.
- Sunny mudbanks where gators bask to warm up
- Still backwaters near cypress roots
- Open marsh edges early and late in the day
How Do You Photograph Alligators Safely?
Great gator photos come from patience and light, not from getting closer. Follow these rules:
- Shoot the 8:00 am or late-afternoon departures for soft, low light.
- Stay seated and let the captain position the boat — never lean out.
- Use zoom rather than proximity; never feed or bait wildlife.
- Keep a strap on your phone or camera on the airboat.
For more, see our weather and swamp tours guide and the full ultimate New Orleans swamp tour guide. To ride, choose a small airboat (6–10 passengers), a large airboat (15–27 passengers), or the shaded covered pontoon.
Every tour lasts 1 hour 45 minutes and departs about 30 minutes from downtown. Pricing varies by boat and season, so call 504-618-1692 for current rates, or book online with a top-rated Cajun crew.
