BOO! Halloween (Scottsdale, AZ, USA) 2026

BOO! Arizona returns on 30 and 31 October 2026 at WestWorld of Scottsdale, the first Arizona edition of Insomniac’s Halloween brand since 2019. Both nights run from 6 PM until 2 AM at the large indoor and outdoor events complex on North Pima Road, where the event is built around the BOO Haunted Mansion concept and two Halloween themed stages. Passes went on sale for a 10 dollar deposit in general admission and VIP tiers, the latter adding an expedited entry lane, a dedicated viewing area and private restrooms, with all VIP areas restricted to guests aged 21 and over.

The bill runs to 30 announced acts across the two nights. The Chainsmokers and Zedd lead it, with Seven Lions, Deorro, James Hype, ACRAZE, Dombresky, Maddix and JAY PRYOR covering the house and main stage side, while Level Up, Restricted, Peekaboo, Virtual Riot, Kompany, HVDES, Samplifire, Sippy and JSTJR handle the bass and dubstep end. Trym and Marie Vaunt bring techno into the programme, Fieldz play back to back with Mile32, and 2DY4, Capochino, GRAVAGERZ, HEYZ, LUGH!, papajay, Alyssa Jolee and Zoe Gitter fill out the rest. One slot is held for the winner of Insomniac’s Discovery Project.

The last Arizona edition landed at Rawhide Event Center on 19 October 2019, an 18 and over show presented with Relentless Beats that featured Deorro, Drezo, SayMyName, Slushii, Bleep Bloop and 13. Seven years on, the revival moves the music festival to a larger Scottsdale site and stretches it from one night to two. Insomniac pitches BOO as a place of paranormal activity and strange happenings, and the production follows that brief with costumes, themed environments and roaming characters running through both evenings. Tickets are sold through Front Gate Tickets, and the official travel page carries directions and parking for the venue.
