You can tan on hot beaches filled with beautiful people, navigate through two-and-a-half lifetimes worth of bars (yes, that's statistically accurate) and head to the notoriously hedonistic nightclubs that are packed till sunrise
Although New York is called "the city that never sleeps," that moniker really belongs to Barcelona, which could just as accurately be labeled, "the city that naps in the afternoon and then parties till sunrise."
Barcelona's nightlife scene has something for everyone, but especially for those who love live music. The vibrant culture provides this city with the perfect atmosphere to kick back and enjoy some mellow tunes or bust some moves to an enthusiastic DJ.
Barcelona has it all: beautiful beaches, unique modernist architecture and a friendly, liberal attitude. Throw in the fact that it's relatively inexpensive, and it would be hard to find a better place to visit while backpacking.
