Beat the Heat With These Free (Or Nearly Free) Options
If you’re searching for indoor activities for kids in St. Louis or free family attractions that won’t break the bank, I’ve got you covered. Summer in St. Louis is beautiful… until it’s 97 degrees, the humidity is at full force, your toddler still has endless energy, and you’ve already changed shirts twice. These are three of my favorite places to escape the heat while keeping little ones entertained all summer long.
Whether you’re planning a rainy-day adventure or just need an air-conditioned afternoon out of the house, these family-friendly spots are worth adding to your summer bucket list.

My go-to is the Missouri History Museum in Forest Park — general admission is free, parking is free, and they run story times and scavenger hunts all summer long, so it never feels like the same visit twice. The Saint Louis Science Center is another favorite, with hundreds of free hands-on exhibits (you’ll pay extra for the planetarium or OMNIMAX, but the main floors are free). And if your kids are into trains, the Frisco Train & Toy Store in Valley Park is a completely free hidden gem with a 16-foot multi-level train table that’ll buy you a solid hour of peace.
