1/13 Panama City Beach, Florida

Panama City Beach practically exists because of Spring Break. It's one of the first places that come to mind for most people when thinking about week-long parties, the beach and questionable decision making. The city is filled with wild parties and is often referred to as the "Spring Break Capital of the World." 

World-renowned DJs lead the massive crowds while all sorts of competitions like twerking and wet t-shirt contests take place. The city hosts nearly a half-million co-eds every spring, keeping them entertained with beautiful sandy beaches, outdoor concerts and bars with extended happy hours in addition to the crazy contests. If you get bored with all that, there's even an amusement park - just don't imbibe too much before getting on that roller coaster.
