National Scavenger Hunt Day : Unleashing Adventure, One Clue at a Time

 

Every year on May 24, thrill-seekers and puzzle lovers across the U.S. celebrate National Scavenger Hunt Day—an unofficial but fast-growing holiday that turns ordinary days into epic quests.

  • Schools use scavenger hunts to teach history, science, and even math (e.g., "Fibonacci sequence" treasure trails).
