The Arch is a St. Louis classic! There's a nice museum, and if you're unafraid of heights, you can take a tram to the top of the Arch for an excellent view of St. Louis.
Possibly the best pizza in existence.
The Italian neighborhood of St. Louis. Come here for pizza, gelato, and bocce ball if you're looking for some fun times!
Beautiful park for a nice walk. We'd recommend the Art Museum for adults and the Nature Playscape if you've got children, both of which are free to all visitors! The Zoo is also a lot of fun, and is also free!
Incredible ice cream! Definitely worth a visit.
This is a wonderful farmer's market to explore. Plenty of good food and window shopping.
