Philadelphia, Pennsylvania is one of the most important cities during America’s Revolutionary War-era. It’s a city of many firsts! “The Mural Capital of the World” is home to the famous Liberty Bell, the U.S. Mint., Betsy Ross’s home, The National Constitution Center, and tons of other educational and historic sites. Race up the famous “Rock Balboa steps” like the inner pro-athlete you are before savoring one of the many delicious meals “The City of Brotherly Love” has to offer, such as the philly cheesesteak. This is a great add-on destination to a NYC or Washington DC trip, or a shorter excursion with groups of any age.
