The 10 Best Haunted Houses & Halloween Haunts in Thornton, CO (2026)
·
The 10 haunts FrightMaps fans like most in Thornton, CO this season — with photos, what to expect, and directions to each one.
How we picked
Every haunt here is a live FrightMaps listing in Thornton, CO. We order by fan likes on FrightMaps, then by how much the listing says, then by whether it has a cover photo. A listing needs a cover photo and at least one like to be ranked here. Pro status and paid placement never affect the order. Ranks were locked when this list was published and do not move for the rest of the season — a haunt that leaves FrightMaps leaves an empty slot rather than shifting the numbers. The 2027 list rebuilds from scratch, so posting dates and photos now is how you move up.
