Electronic dance music's premiere festival Tomorrowland takes place every July in Boom, Belgium. More than 400,000 attended this year's 10th anniversary event. 

Top international DJs play amidst a backdrop of the most elaborate, colorful and exhilarating stage setups in the world. Festival grounds are decorated to lead attendees on a journey through oversized forest and flower landscapes, outlandish costumes, mythical creatures, smoke, lasers, and much more. It's a spectacular visual explosion in every direction.

Next year's festival will take place July 24-26 in Boom, and ticket sales have yet to be announced.
