From nightfall to midnight, roam the River Walk with eerie sounds, friendly roaming ghouls, and zombies.  Enjoy music, dancing, an adult costume contest (18+), haunted river parade, and trick or treating to round out a slightly-spooky night of fun. This is a very popular event; come early and stay late. The vibe is spooky but not too much for scaredy-cats. Bwaahaahaa!
