What Locals Say about O Fallon

Review Highlights

O'Fallon, IL: easygoing suburb with lively parks, top schools, quick St. Louis access. Safe, walkable, park-rich, with great schools and an easy 20–25 min St. Louis commute. Some pet issues and limited buzz; occasional mild traffic, most errands need driving.

"I’ve lived here 5 years. All of the neighborhoods have sidewalks and are walk-able. I like that the schools and churches are within the neighborhoods. For the town size, there is a large number of well maintained parks. Super cute downtown with lights, local restaurants, bars, and farmers market. Big bike trail system that spans multiple counties. Super close to St Louis- about a 20-25 min drive to Busch Stadium. Easy commuting distance to AFB- about 10 minutes. Good city council and police department. Good school system. "
