Nocturnal Wonderland will return to Glen Helen Regional Park on Sept. 19 and 20 for its 31st edition, bringing another two nights of electronic music, camping and late-night festival production to the foothills of San Bernardino. The festival runs from 3 p.m. to midnight each day and remains one of the few major Southern California dance festivals built as much around its outdoor setting as its stages.
This year’s lineup stretches across house, bass, drum and bass and melodic electronic music. Saturday brings deadmau5, James Hype, Green Velvet, Deorro, Malaa, NGHTMRE and SVDDEN DEATH, alongside sets including INFEKT b2b Virtual Riot, Hybrid Minds and Patrick Topping. Sunday shifts toward ILLENIUM, Seven Lions, SIDEPIECE, R3HAB, Dombresky, Hedex and TroyBoi, with Said The Sky scheduled for a sunset set and T-Pain appearing under Teddy Pain for a bass-focused DJ set.
That range has always been part of Nocturnal Wonderland’s appeal. Rather than centering the weekend around one corner of electronic music, the festival spreads different sounds across Mystic Wild, Dawn Mountain, Aurora Plains and Rave Cave, giving the weekend room to move between large-scale headliners and heavier or more specialized sets. Bassrush Experience and Insomniac’s rave-focused programming also return as part of the festival.
The setting is another major part of what separates Nocturnal from Insomniac’s other Southern California events. Glen Helen Regional Park covers more than 1,300 acres beneath the San Gabriel and San Bernardino Mountains, allowing Nocturnal to lean further into its woodland, after-dark identity than festivals held at traditional event centers. Art installations, costumed performers and immersive stage environments are built into that world rather than treated as decoration around it.
For campers, the weekend starts before the gates officially open. The campground runs from Friday, Sept. 18 through Monday, Sept. 21, with a Friday pre-party, nightly silent discos, open decks, yoga, crafts and other activities extending the festival beyond its two main days. Tent and waterfront camping remain available, while several other camping options have already sold out.
More than three decades in, Nocturnal Wonderland does not need to reinvent what it is. Its combination of a broad electronic lineup, camping and the open landscape of Glen Helen remains distinct within Southern California’s crowded festival calendar. With deadmau5 leading Saturday and ILLENIUM, Seven Lions and Teddy Pain among Sunday’s draws, the 2026 edition gives that formula another particularly wide-ranging lineup.
