8. Barcelona, Spain
There are many reasons why you should visit Spain if you are looking to party. If you had to choose only one city to visit in Spain, pick Barcelona.
It is the home of the Spanish infamous tradition: San Fermin festival. In the heart of Navarra, every year around July, the streets are flocked with people and… a dozen of bulls!
In the other part of the city, there are many live bars where the locals dig into their tapas. Nightclubs are lining up with large variety of beat. From live music, dance music, to Las Ramblas, the choice is yours.
If you visit the city during summer, do not miss their Summer dance festival of Piknic Electronik which takes place every Sunday at Jardins de Joan Brossa.
