Boombamela is a formerly New Age-oriented and more recently mainstream festival held annually on Chol HaMoed Pesach (Intermediate Days of Passover) in Israel since 1999. The inspiration for the festival is the Hindu festival of Kumbh Mela. Its organizers have described it as "a place for meeting, experiencing, crossing borders and transcending social limitations through music, creation, and connection with nature." The festival is located on the remote sandy beach of Hof Nitzanim, between Ashdod and Ashkelon.
The festival has risen in popularity and prominence over the years and is now perhaps the most famous of Israel's festivals (challenged only by Tel Aviv's summer Love Parade). The seventh Boombamela, in 2005, attracted 36,000 visitors - the third highest, after 2004's 41,000 and 2003's 37,500. More and more foreigners have taken note of the festival, and a visitor will often hear various other tongues being spoken beside Hebrew.
