Aurora is the second-largest city in Illinois and is known as the City of Lights because it was one of the first cities to use electric street lights. It sits along the pretty Fox River.
You can catch a show at the beautiful old Paramount Theatre, learn about space and science at the SciTech Hands On Museum, or stroll along the Fox River trails.
Aurora's downtown wraps around the Fox River with bridges, cozy shops, and the grand Paramount Theatre lit up at night like a jewel.
The SciTech Hands On Museum lets kids touch and play with fun experiments, making learning about light, sound, and machines a real adventure.
