Nocturnal Wonderland is an electronic dance music festival founded in 1995 and held annually near Labor Day weekend in San Bernardino, California, drawing around 50,000 attendees across trance, house, drum and bass, techno, and hardstyle programming. Produced by Insomniac Events, it has been staged at the Glen Helen Amphitheater every year since 2013.
Its long-running EDM identity and large production scale make it a substantial festival entry.
Now three decades old, Nocturnal Wonderland is one of the longer-running electronic dance music festivals in the country, predating the mainstream EDM boom of the 2010s by well over a decade and helping establish Insomniac Events, its longtime producer, as one of the genre's dominant promoters
The festival's genre range is notably broad, spanning trance, house, drum and bass, techno, and hardstyle across roughly five stages and around 60 artists over its two-night run, giving it a more eclectic identity than festivals built around a single subgenre
Its long tenure at Glen Helen Amphitheater since 2013 has made the venue part of the festival's identity, even as noise ordinances briefly threatened another relocation in 2019 before organizers found a way to keep the event there
The festival's defining tradition is its late-summer timing around Labor Day weekend and its multi-stage format spanning a wide range of electronic subgenres under one event
a structure it has maintained since its 1995 founding even as its venue and producer relationships have changed over three decades
