We had to start this guide off with one of the metro area’s most boast-able free attractions. Although nonmembers will still drop some money on parking and select attractions, the Saint Louis Zoo is one of the few remaining free zoos in the U.S. Visitors have the chance to view more than 16,000 animals and 500 species. It’s practically a St. Louis summer rite of passage.

Start with a tram ride to view a variety of animals, and spend most of your day at the petting zoo.

This free museum has several exhibits worth checking out for those interested in their local history, but the History Clubhouse specifically is the big draw for kids here.
