Valley Forge Self-Guided Mystery Game

Turn Valley Forge National Historical Park into a mystery to solve, with a self-guided game played on your phone and no fixed schedule. Choose one of three adventures, each unfolding across five to seven historic stops. Washington’s Secret Soldiers invites junior agents ages 6–12 to crack Revolutionary War spy messages and deliver a lost battle order. In Lafayette’s Dispatch, step into the Marquis de Lafayette’s role, collect a letter at each monument, and send a dispatch to win an ally. The Mystic Tie follows the Freemason bonds among Washington’s officers as you decode a hidden word.

Each game stands alone and takes about 1.5 to 2.5 hours at your own pace. Explore on foot or by car, starting at the Visitor Center: park in its lot, open the game link on your phone, and begin Stop 1. There’s no in-person check-in, so you can start when it suits you. Valley Forge self-guided mystery games bring the park’s history into an interactive outing for your group. Choose your adventure and set out to uncover its clues.
