Nauvoo is a small Mississippi River town with a population of around 950 residents, yet it welcomes nearly 100,000 visitors each year. Perched on a scenic bluff overlooking the river, Nauvoo’s main shopping and dining district is centered along Mulholland Street, primarily in the 1200–1400 blocks, where visitors will find locally owned shops, restaurants, lodging, and small-town charm. Just down the hill along Main Street is the Historic District, home to restored homes, shops, and interactive historical reenactments that bring 1840s Illinois to life. Visitors can explore traditional trades and learn more about the history of The Church of Jesus Christ of Latter-day Saints and the people who once called Nauvoo home. The Historic Sites are open year round seven days a week and are free of charge to tour. The shopping district on Mulholland Street has shopping that is primarily seasonal with May to October being the primary months. Most of the business district is closed on Sunday except Baxter's Winery, Casey's Gas Station, and Dollar General that will be open.

One of the most common comments from visitors to Nauvoo is about the variety of bugs! The local insect population can be surprising if you're not used to it. The most unusual of these is the mayfly. These short-lived, messy insects appear in large numbers for a few days, typically in the summer. They only live for one day, but during their brief appearance, they are everywhere. Though they can be overwhelming, they are completely harmless.
In the summer, mosquitoes are prevalent, and after dark, it’s recommended to use bug spray. During the day, you'll also encounter biting gnats. These are repelled by vanilla or specialized gnat sprays, but regular bug spray doesn't deter them. And don’t forget about chiggers, which live in grassy areas and can cause an itchy rash. If you're planning a picnic, it's a good idea to use a blanket and avoid sitting on the grass for long periods.
But not all bugs are unwelcome! Our favorite is the lightning bug or firefly. Watching them light up a summer evening is pure magic and one of the most enchanting sights you can experience in Nauvoo.
