a drive up through some nice neighborhoods and enter the park. It's a short hike up some dirt roads; more accessable than a trail since film crews need to haul their equiptment to shoot. look around & you'll see one of the best views of the hollywood sign.
the cave ( really a tunnel) is surrounded by hugh cliffs. the whole area used to be a mining operation, thus giving it an unnatural other world look that some productions want to have. A must see for fans of westerns and scifi films, including TV shows like Batman.
