We are delighted to be back for our 26th year of Halloween haunting in Covina!  We will be open three evenings on Halloween weekend for folks to experience Vertigo Alley, our amazing walk-through tunnel of fun.  Come on by, see the new things we've built, and enjoy Vertigo Alley.  

Welcome to Maniac Mansion, the home of haunt mavens Thomas Henke and Monica DiFranco, as well as dozens of spectral and spooky apparitions that make Halloween the most fun day of the year.  Located in the charming city of Covina, an eastern suburb of Los Angeles, dominated by beautiful views of the San Bernardino Mountains.
