If you’re going to explore Philadelphia during the night, make sure to stick to well-lit, populated, policed areas as areas outside of the main tourist attractions of Philadelphia are not the safest and could pose a risk if not careful.
Ensure that your personal belongings are always safe on you, as pickpocketing is not that frequent, it still happens, make sure your phone, wallet and other personal items are close to you all the time.
Familiarise yourself with the city in advance, make a map or a plan of action for your time there to get the full experience of Philadelphia. Make sure to immerse yourself in the Philadelphia experience but be mindful of your surroundings and belongings
