Ibiza Island has become a name synonymous with party and wild nights. Situated around 80 Km away from the mainland of Spain, Ibiza Island has slowly crawled into the list of most visited tourist attractions in Spain. Apart from partying hard, there are many other things to see and experience. In fact, a large part of Ibiza is recognized as a world heritage site by UNESCO. The island is best visited during summers when most of the clubs are operating and are full of people. But if you are looking for quieter times, then September to May is the best time.
