Happening in June in Seoul Olympic Stadium, the Ultra Korea festival is known as the biggest electronic dance party in Asia and for a good reason—one can find top class DJ’s from all over the world, light shows, pyrotechnics, and swimming pool parties. Expect nothing less than an epic experience with both the performances and the lively crowd. The entry passes are available for purchase on-site but make sure to check the official website because tickets may be cheaper via online reservation. Act early because passes may be limited! In June 2016, it is the festival's 5th anniversary, so it is going to last three days!
