43 dated events
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, a climbing gym in costume. 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.
43 dated events across 35 attractions, by region. Many are on selected nights only and several are ticketed separately — the venue’s own page, linked under every quote, is the one that sells them.
