iFLY Chicago Naperville is a 14-foot (4.3 m) recirculating tunnel in Chicago, Illinois. It is currently one of the three places to go indoor skydiving in Chicago, alongside iFLY Chicago Rosemont and iFLY Chicago Lincoln Park. The Generation 6 iFLY Naperville was the second indoor skydiving Illinois location, opening a month after the identical iFLY Rosemont (both opened in mid-2014). iFLY Lincoln Park, the city’s third tunnel, opened in 2016.
This location serves the entire Chicagoland area. The tunnel sits just off I-88 and is easily accessible from the interstate and the surrounding communities, such as Aurora, Wheaton, Downers Grove, Bolingbrook, and Joliet. Naperville is closer to the large Chicago dropzones, such as Chicagoland Skydiving Center and Skydive Chicago. As a result, it sees more skydivers in the summer months than other indoor skydiving Chicago locations. Because of the many surrounding neighborhoods, this location often features events, birthday parties, and more.
