The Haunted Trail of Balboa Park
The Haunted Trail is a mile long "stroll" through the park you will never forget. This terror of twisted pines and gnarled oaks is not for children under 10 or the faint of heart. For a few extra bones you can experience the Carnival of Carnage Maze, over 3500 SF of carny infested terror.
