The Haunted Hotel at 424 Market St. is scheduled to open at 6 p.m., while the Haunted Trail along Balboa Drive near Juniper Street is set to kick off its 2013 season at 7 p.m.
Visitors to the Haunted Hotel take an average 15-20 minutes to stroll through the spooky establishment, while costumed characters attempt to scare them.
The Haunted Trail is a mile-long trek through a darkened section of Balboa Park; it promises to scare visitors with surprise encounters.
The same company puts on both events annually. This year’s events will run through Nov. 2. Tickets for each start at $15 and can be purchased at hauntedhotel.com.
