Nocturnal Wonderland is a two-day event (a three-day festival from 2011 to 2016) that used to occur in early September around Labor Day.

The genres present at the festival vary between trance, drum and bass, breakbeat, and house.

The locations varied every year, but since 2002 the festival has taken place at the National Orange Show Events Center in San Bernardino, where it was first held in 1998.

The show went on hiatus in 2020 due to the COVID-19 pandemic, however, they did host a Virtual Rave-a-thon in place of the in-person event.

In 2021, the live event returned and took place at Glen Helen Regional Park annually.
