Universal Orlando has drawn a battle line in haunted house history: Halloween Horror Nights 35 — Infernal Carnival of Nightmares — marks the first time the event’s two most iconic figures, Jack the Clown and Dr. Oddfellow, join forces rather than compete. Running August 28 through November 1, 2026, HHN 35 promises 10 all-new haunted houses, expansive scare zones, live entertainment, and the full spectacle that has made it the most-attended haunted house event in the world year after year. If you’re planning a visit — whether for the first time or the thirty-fifth — this is your complete planning guide.

HHN 35: The Theme and Icons

The Infernal Carnival of Nightmares concept leans hard into the circus-horror aesthetic that Jack the Clown has always personified, but with a narrative twist: Jack and his long-running rival Dr. Oddfellow, whose battle for dominance has threaded through multiple HHN events, are now aligned. The 35th anniversary unites the devious duo in a shared carnival of chaos — and that partnership serves as the story engine driving this year’s haunt lineup and scare zone design. For longtime HHN fans who’ve followed the lore, this is the payoff of decades of narrative buildup.

The carnival framing also gives 2026’s event an aesthetic distinctiveness from recent IP-heavy lineups. While licensed properties will still feature prominently in the 10 haunted houses, the carnival theme anchors the scare zones and live entertainment in an original HHN identity that Universal hasn’t leaned into this fully in years.

Confirmed Haunted Houses for HHN 35

Jack and Oddfellow: Chaos and Control

The event’s first officially confirmed house places guests directly inside the feud-turned-alliance. This original IP experience walks visitors through the history of Jack and Oddfellow’s decades-long conflict, ultimately arriving at their shared carnival nightmare. Production values for original IP houses at Universal are consistently among the best at any theme park event in the world — expect cinematic set design, aggressive live talent, and scares engineered around the characters’ known aesthetic rather than IP licensing constraints.

Nine additional houses are confirmed for HHN 35. Universal typically announces haunted houses in waves between April and August, with the full lineup usually locked by late July. Licensed properties from major horror franchises regularly feature at HHN — previous years have included The Exorcist, Chucky, Blumhouse properties, and original concepts. 2026’s additional announcements will be updated here as they’re confirmed.

Event Dates, Hours, and Tickets

Planning Your HHN 35 Visit: Practical Strategy

When to Go

HHN attendance patterns are predictable: opening nights in late August are the least crowded and often most intense in terms of actor performance energy; mid-October fills rapidly; Halloween weekend is maximum-capacity chaos. For the best balance of manageable crowds and full experience, target Thursday or Sunday nights in September or early October. The event runs late — 2:00 AM closing on most nights — which means arriving at park opening and working backward is a viable strategy for completionists who want all 10 houses.

Express Pass: Worth It at HHN?

More unambiguously than at most events: yes. HHN wait times on Friday and Saturday nights in October routinely hit 60–90 minutes per house. Without Express Pass, completing all 10 houses in a single night is nearly impossible on busy evenings. Express Pass cuts waits to 10–20 minutes per house. If you’re traveling from out of town and have a single-night ticket, Express Pass is the difference between seeing 4 houses and seeing 10.

Park During the Day?

HHN tickets are evening-only admission. If you’re also visiting Universal Studios Florida during the day, that’s a separate park ticket. Many visitors book a day/night combo — theme park during daylight, HHN after 6:30 PM — which is excellent value given Universal’s ride lineup. The theme park officially closes as HHN begins, with day guests exiting designated areas. Check Universal’s current combo ticket options when booking.

Orlando Haunted Houses Beyond HHN 35

If you’re visiting Orlando for the haunt season and want to experience local options beyond Universal, Florida’s haunted attraction scene is robust. Central Florida haunts like Howl-O-Scream at Busch Gardens Tampa, as well as independent local haunts, compete at a high level during October. Browse Haunt Harvester’s Florida haunted house guide for the full regional picture, and use our near-me finder to see what’s running when you’re in town. For a broader overview of what makes professional haunted houses worth visiting, our haunted house hub has everything you need before your first or fiftieth visit.

HHN 35 vs. Other Major Haunt Events in 2026

Halloween Horror Nights is the largest single-venue haunted attraction event in the world by attendance, but it’s not the only marquee experience worth planning travel around. Howl-O-Scream (Busch Gardens), Knotts Scary Farm in California, and regional touring extreme haunts all compete for serious haunt-goers’ fall calendars. HHN’s advantage is the concentration of production value and IP access under one roof in a single evening. Its limitation is the cost — a fully loaded HHN night with Express Pass is a premium-price experience. Know what you’re paying for: it’s the world’s best haunted house event, not a haunted house deal.
