With over 16,000 square feet of pure unadulterated terror, the Slaughter House in downtown Dallas, is a haunted attraction that has a claim as the most intense haunted house in Texas. Purported to be the abandoned remains of a decrepit old slaugherhouse, the Slaughter House uses a terrifying combination of tension, shock and gore to give its guests a harrowing and gut-wrenching experience they’ll never soon forget. Both individual and group rates are available, and coupons can be found online for reduced admission. They are open only for the Halloween season, so be sure to show up after dark for the best experience.
