Halloween events in Illinois

10 Halloween events at 5 Illinois attractions, running Sep 25 to Nov 1. Trick-or-treat trails, haunted houses and pumpkin nights, with prices and times on each venue’s page.

Everything here is a dated event a venue has published on its own website: fright nights and family haunts, trick-or-treat trails, boo-at-the-zoos. Fall festivals with a corn maze and a scarecrow are autumn rather than Halloween and sit on the pumpkin page instead; a Day of the Dead remembrance is its own tradition and is not filed under this one.

What’s on

10 dated events across 5 attractions, soonest first. Many are on selected nights only and several are ticketed separately — the venue’s own page, linked under every quote, is the one to check before you set off.
