This past weekend, Tomorrowland 2024 kicked off its 20th anniversary in arguably one of its most epic opening weekends yet. Over its three days, the dance festival in Boom, Belgium welcomed roughly 400,000 festival goers, who came from around the world and arrived decked out in eye-catching and photo-worthy costumes and summer attire. With temperatures soaring over the weekend, these types of outfits were essential.

July 19-21 marked the first weekend of Tomorrowland 2024, along with some of the hottest temperatures the festival has experienced, with the daily heat climbing up to 90 degrees, compared to the average 70-degree temps. Hot weather couldn’t stop the party, though, as DJs brought their A-game with playlists filled with crowd-rousing beat drops, enthusiastic calls for attendees to put their hands in the air and an overall sense of community.

Tomorrowland’s stages have always been feats of technology and whimsy, and 2024 was no exception. The festival’s 20th birthday wasn’t just a milestone moment for the event itself, but a celebration of life — which was also revealed to be the theme for this year, with multiple elements of the event taking inspiration from this idea.

With the site clocking it at roughly 9,000 acres, walking from stage to stage is a full-on experience where one encounters art, fellow attendees, performers and delicious food booths ready to fuel you up for the next dance session. Of course, the who’s who of the electronic music world were on site for the event, with hundreds of DJs including Swedish House Mafia, Tale of Us, Alesso, Amelie Lens, Bonobo, Dom Dolla, The Blessed Madonna, REZZ and Deadmau5 performing as REZZMAU5, David Guetta, Solomun b2b Four Tet, Eliza Rose and many others all playing over the weekend.

From mesmerizing stages to surprise guest appearances — and ahead of the second weekend of the festival starting this Friday, July 26 — below are all the moments from Tomorrowland 2024 we won’t be forgetting any time soon.
