Most of the film was shot in Santa Cruz, California; locations include the Santa Cruz Boardwalk, the Pogonip open space preserve, and the surrounding Santa Cruz Mountains. Other locations included a cliffside on the Palos Verdes Peninsula in Los Angeles County, used for the entrance to the vampire cave, and a valley in Santa Clarita near Magic Mountain, where introductory shots were shot for the scene where Michael and the Lost Boys hang from a railway bridge. Stage sets included the vampire cave, built on Stage 12 of the Warner Bros. lot, and a recreation of the interior and exterior of the Pogonip clubhouse on Stage 15, which stood in for Grandpa's house.
