Aside from greeting the western United States from atop the Gateway Arch, there is no shortage of Saint Louis activities for visitors to enjoy. Whether you’re a kid or just want an excuse to act like one, a stop at the St. Louis City Museum is a must. You can easily spend an entire day here, but if you have limited time, be sure to check out the 10-story slide. The list of things to do in St. Louis doesn’t end there, though. View more than 30,000 works of art at the Saint Louis Art Museum, then walk over to the award-winning Saint Louis Zoo. There are also plenty of outdoor beauties on display at the Missouri Botanical Garden.
