Have a blast at Six Flags St. Louis! Part of the Six Flags franchise, this theme park features dozens of rides and attractions, shows, a water park, and a day's worth of fun in the sun for the whole family.

Bring your magnifying glass to the smallest tourist attraction in St. Louis. The Miniature Museum of Greater St. Louis is devoted to miniatures of all sizes, from small to itty-bitty to teeny-tiny. Visit the gift shop, take a class, or attend the twice-yearly Gateway Miniature Fair. The museum is open Wednesday through Sunday.

Whether you're celebrating your heritage or just there for the green beer, the St. Patrick's Day Parade has something for everyone. One of the longest-running St. Patrick's Day parades in the country, this St. Louis festival offers marching bands and floats to celebrate this favorite Irish holiday.
