Tomorrowland Belgium was founded in 2005, making this its 21th year.
The festival is part of We Are One World's portfolio of electronic music events.
Tomorrowland has run every July since 2005 at De Schorre park in Boom, Belgium, growing from a local gathering into one of the largest dance music festivals on earth. Organized by We Are One World, it drew attendees from more than 200 countries and peaked at roughly 600,000 visitors across three weekends in 2022, when the custom mainstage measured 270 meters wide and 53 meters tall. The 2026 edition runs two weekends (July 17-19 and July 24-26) under the theme "Consciencia", with Martin Garrix, Calvin Harris (his Tomorrowland debut), David Guetta, Tiesto, and Hardwell confirmed as headliners. The festival has broadcast online longer than most of its competitors have existed: the YouTube channel has cleared 2.2 billion views, the 2020 and 2021 "Around the World" paid virtual editions each drew more than a million viewers, and a 2025 TikTok partnership set an all-time platform record at 74 million viewers. Each year, 99 to 125 full sets go up on YouTube at no charge. On Ravestreams, you can watch every stage as it happens or catch any set you missed.

Tomorrowland has one of the deepest livestream track records in festival history. It moved from YouTube sets and a dedicated multi-view app in the mid-2010s to a full proprietary broadcast network. When COVID cancelled the 2020 in-person event, the festival produced 'Around the World', a fully rendered virtual edition with paid tickets, custom 3D stages, and over a million viewers, a model it repeated in 2021. From 2022 it rolled out One World TV and One World Radio as its own free multi-channel infrastructure, streaming main and secondary stages 13-plus hours daily across both weekends and the days between. The TikTok era arrived in 2023 with 16 million unique viewers as official content partner, growing to 74 million in 2025, a new all-time record for a live event on the platform. The festival routinely publishes 99 to 125 full recorded sets per edition for free on demand.
Every edition is built around a theatrical theme with a custom mainstage that ranks among the largest temporary structures in the world; the 2022 stage measured 270 metres wide and 53 metres tall.
The festival draws attendees from more than 200 countries and employs roughly 15,000 people on site, making it one of the most internationally attended music events anywhere.
Its YouTube channel, launched in 2011, has passed 2.2 billion views and 11 million subscribers, with full set archives posted free after every edition.
Tomorrowland was among the first major festivals to produce a fully rendered virtual edition (2020), using custom 3D green-screen studios across four countries rather than a simple studio stream.
The festival takes place at De Schorre, Boom in Belgium. It typically hosts crowds in the 400,000+ range across 10 days.
