While at Universal Studios Orlando, the Halloween Horror Nights event starts at 6:30 p.m. and closes at 2:00 a.m. every event night.

In 2026, the closing time for Halloween Horror Nights (HHN) at both Universal Studios Florida and Universal Studios Hollywood depends on the specific night of the week. On "peak" nights (Fridays and Saturdays), the event typically ends at 2:00 AM. On "off-peak" nights (Wednesdays, Thursdays, and Sundays), the fog clears and the gates close at 1:00 AM. The event usually begins at 6:30 PM, though "Stay and Scream" guests already inside the park can access select houses as early as 5:30 PM. In 2026, Universal has introduced "Last Call" warnings via their mobile app 30 minutes before the event ends to help manage the massive crowds exiting the scare zones. It is important to note that while the event may "end" at 2:00 AM, the lines for the most popular haunted houses often close earlier if the wait time exceeds the remaining hours of the event. To maximize your time in 2026, arriving for "Early Admission" or purchasing an Express Pass is considered essential.
