Designed by a father-son team for families with kids ages 6-12, this self-guided escape game turns Valley Forge National Historical Park into a five-stop spy adventure. Decode messages hidden by a young Continental Army agent, count clues only visible on-site, and learn the real history of how Washington's starving army survived the winter of 1777-1778 — meeting Baron von Steuben, the Prussian general who transformed farmers into soldiers, and discovering why this brutal encampment became the turning point of the American Revolution. Play at your own pace, anytime the park is open.
