"It’s no secret that Philadelphia has some of the US’ most important historic sites. If you’re visiting to experience some of that history, don’t just limit yourself to the city boundaries. Valley Forge, a 35-minute drive away, is the spot where George Washington’s army suffered through a harsh winter during the Revolutionary War. Exhibits include group tours of the encampment, Washington’s headquarters, and artillery park with real Revolutionary-era cannons. In addition to the history, Valley Forge is also a park with 19.5 miles of hiking trails and 21 miles of biking trails. After checking out the history, you can unwind by hiking or biking; you can rent bikes over the weekends in spring and fall, and every summer day, at the Encampment Store. Pick up food before you go and enjoy a picnic at the park; there are several designated picnic areas and even grills for a cookout." - MATADOR_NETWORK
