French environmental groups challenge Tomorrowland Winter over alleged illegal noise pollution

The organisations argue that previous editions of the festival exceeded legal sound limits, affecting both local residents and the surrounding mountain environment. Tomorrowland Winter is scheduled to return on March 21, 2026, attracting more than 22,000 attendees to the ski resort.

“Behind the glitter lies disruption for local residents,” Mountain Wilderness wrote, claiming the alpine landscape risks becoming a backdrop for a large-scale event with little regard for environmental balance or community wellbeing.

According to the groups, local authorities failed to respond adequately to earlier concerns, prompting them to escalate the matter to the Grenoble public prosecutor. In addition to noise levels, the organisations criticised the environmental impact of air travel linked to the festival and questioned the legality of recent infrastructure expansions, including modifications to a local football field allegedly funded with public money.

In response, Tomorrowland emphasised its compliance with French regulations. Spokesperson Debby Wilmsen said the festival works closely with local authorities and remains open to dialogue with residents. She also highlighted that Tomorrowland Winter operates primarily as a daytime event, with mountain stages closing by 16:30 and village stages shutting no later than 01:30.

Wilmsen added that sound becomes inaudible beyond 200 meters, and noted that the festival takes place during winter, when most wildlife remains in hibernation.
