At 1,135 ft high in the hills of Griffith Park, Griffith Observatory is the crown jewel of Los Angeles. On a clear day, gorgeous views of Los Angeles, Hollywood and the ocean are seen for miles. It has been free since opening its doors in 1935. Colonel Griffith J. Griffith donated his land to the city in what would become a great park as long as a planetarium was built. He wanted a place where all could explore and enjoy astronomy. The Observatory was made famous by its appearance in the iconic James Dean Film 'Rebel Without A Cause'.
