Bronson Caves


Bronson Caves are located in the southwest section of Griffith Park and is thus easily accessible from Hollywood. From Franklin Avenue, one can go north on Canyon Drive until the road ends for vehicular traffic at the parking lot for "Camp Hollywoodland". At the right (east) side of the road is a small concrete bridge painted red. One can cross the bridge and walk around the vehicle barrier, and follow the unpaved road, keeping left, for the short walk into Bronson Canyon.


In 1903, the Union Rock Company founded a quarry about two miles north of Franklin Ave., at the northern end of Bronson Ave.  The area was known as Brush Canyon.  The crushed rock was trucked down Bronson Avenue for use in railroad ballast and street surfaces.


Many Hollywood residents complained that the trucks tore up the newly paved streets and jarred their homes as they passed in the night, so a rail line was established that operated during restricted hours of the morning and evening. By 1918, it had become more economical and practical to call the rock by truck, so the railroad spur was discontinued.


As a result of complaints from homeowners on Bronson Avenue end of the diminishing need for the crushed rock, the quarry ceased operation in the late,1920s , leaving the caves behind. The caves became known as the Bronson Caves after a nearby street, giving the area its more popular name of Bronson Canyon.


Scenes of the main cave entrance are normally filmed in a manner that shows the entrance at an angle. This is because the cave is actually a very short tunnel through the hill, with the rear opening easily visible in a direct shot. The most well known appearance of the tunnel entrance is likely as the entrance to the Batcave.in  Batman television series of the 1960s.


The Bronson Caves have become famous as a filming location for a large number of movies and television shows, especially westerns and science fiction from the early days of motion pictures to the present. Its craggy and remote-looking setting, but easily accessible location, has made it a prime choice for filmmakers, particularly of low-budget films, who want to place scenes in a lonely wilderness.


To get to the Batcave! At the top of Canyon Drive in Griffith Park, take the fire road on the right heading southeast out of the canyon. After a quarter mile, turn left into the bowl-shaped quarry. You will see Bronson Cave immediately, a drive-through tunnel carved into a 100-foot tall rock wall. There are three exits at the far end of the 50-foot long tunnel. One is big enough for a Batmobile and the others are crawl-through size. Walk right in. No flashlight is needed to explore the short cave.
