The Hollywood Cemetery walking tour is more historical than Halloween; nevertheless, it is appropriate for the October season. I took the tour around Halloween several years ago, and I heartily recomment it. The Hollywood cemetery is a fascinating place, quietly tucked behind Paramount studios. There are many monuments to Hollywood icons and many legends to relate about them.
Tours are being offered every Saturday at noon (not on Halloween itself, unfortunately, because it falls in the middle of the week). Meet at the flower shop by the entrance. Parking is available on the grounds.
