Halloween Horror Nights Hollywood
3 Sep – 1 Nov 2026
The West Coast edition, with the Terror Tram running through the backlot.
The original theme park Halloween event, running since 1973.
Knott's invented this format — the first theme park Halloween event of its kind, and still one of the best. 2026 runs 26 nights with two new mazes.
The scare zones between the mazes are the reason regulars come back; the fog in the Ghost Town streets is thick enough that you genuinely cannot see what is about to reach you.
