Grab casual clothes and head off to the City Museum. It's an adult playground, unlike anything you've ever seen/experienced in downtown St. Louis. Because STL is the best, there's even beer!
If the weather is nice, head to Forest Park--- the jewel of St. Louis. Forest Park is the home to amazing trails, the Art Museum, the Zoo, and so much more!
Is there a game you want to watch?! Head to Ballpark Village! It's downtown, right next to Busch Stadium. There's multiple restaurants to grab a meal at and 3943789234843 TVs to catch your favorite game.
If you're a nerd like Claire... check out the National Blues Museum. It's fun and interactive!
You can't visit St. Louis without making a stop at the Arch! Located Downtown, you can stop by just to see the Arch, or head into the free museum in the basement. For a fee, you can go up in the Arch!
