Six years in, Colorado's horror convention has outgrown its old room and moved to the Denver Marriott Tech Center. That relocation is the story: conventions move venues when attendance forces the issue, and this one did.
The 2026 theme is Clowns vs. Witches. Programming spans author and filmmaker panels, an independent horror film festival, a costume contest, and a tattoo competition, which puts it closer to a working genre conference than a photo-op autograph line.
The weekend runs Friday September 18 through Sunday September 20 at 4900 S Syracuse St in the Tech Center. Hours differ by day and ticket tiers range from single-day to full weekend, so check the official site before buying. The hotel has its own garage, and the Belleview light rail station is about a mile away.
