This Mediterranean island is party central for European revelers, which makes it one of the best bachelor party locations to consider. The electronic music scene here is unparalleled, particularly May through October. Bar hop along the San Antonio or Ibiza Town strips, or rub shoulders with 10,000 of your closest friends in enormous dance clubs like Space, Privilege or Pacha. Book ahead to get VIP privileges for a better bachelor bender experience. Rent a villa as a home base as you’ll need someplace to recover from the night before.
