5. Philadelphia, Pennsylvania
Philadelphia is the largest city in the US state of Pennsylvania and the sixth-most populous U.S. city. It is also one of the oldest municipalities in our country. Just like Atlanta, Philadelphia also offers visitors free admission to some of its most iconic spots. For example, did you know you can snap a photo of yourself next to the Liberty Bell at virtually no cost?
As a matter of fact, you can also walk the rooms of Independence Hall as Benjamin Franklin and Thomas Jefferson once did, all for free. The City of Brotherly Love (Philadelphia comes from two Greek words: phileo which means love and adelphos, brother) is also known for its iconic cheesesteak, so you must enjoy at least one when you’ll visit this city.
