13th Floor Haunted House, 3400 E 52nd Ave · Denver
The venue homepage says tickets start at $19.99. A night-by-night price list is not on the pages we opened.
Select nights Sept 11–Nov 14 at 3400 E 52nd Ave. The venue says it may be too intense for children 12 and under. Halloween-night entry times are from a secondary roundup, not the venue's own calendar.
13th Floor Haunted House Denver lists its address as 3400 E 52nd Ave, Denver, CO 80216. The homepage says the 2026 run is select nights from Sept. 11 through Nov. 14, and that tickets start at $19.99. We did not find a night-by-night calendar on the venue site. The buy-tickets page on the national 13th Floor site was still labeled as an older season, so the specific nights are not confirmed here beyond that date range.
The 2026 attractions named on the homepage are Jason Universe: Survive the Night (an officially licensed walkthrough), The Stitchworks, and Cathedral of the Crimson Queen. The location page warns that the event may be too intense for children 12 and under, and that minors 15 and younger must be with an adult.
Halloween night hours are not on those official pages. Denver Halloween's Oct 12, 2026 roundup, which says it was updated from each attraction's site and ticket calendar, lists Oct 31 timed entries from 6 to 11:15 PM. That window is cited from the roundup, not from a calendar we could open on 13thfloordenver.com. Ticket prices beyond the homepage's "start at $19.99" are left off for the same reason.
