George Washington's Continental Army to Valley Forge and features the first opportunity to see the newly rehabilitated Fort John Moore/Redoubt. Candlelit ranger tours, fife and drum performances, and interpreters will share stories of the encampment. This is a special opportunity to experience Valley Forge at night.
