The caves in Griffith Park are not true caves but rather a tunnel left over from an early 20th-century rock quarry. Crews excavated crushed stone for the construction of L.A. city streets, including the nearby Bronson Street, which lends its name to the canyon and the caves.
The short tunnel through rock is a fun place for kids to explore, and the short, flat hike is perfect for families. Film buffs will particularly love visiting, however. Because of its proximity to Hollywood and easy access, this quarry has appeared in more than 100 movies over the past century, including The Three Musketeers (1933), The Lone Ranger (1956), and The Scorpion King (2002). TV shows have also used this setting, including The A-Team, Batman (1960s), and multiple Star Trek installments. The walk back features a view of the Hollywood sign framed between the canyon's hillsides, reminding visitors of the rich cinematic history of this place.
