The Griffith Park Zoo, also known as the “Old L.A. Zoo,” opened in 1912 and was on the verge of shutting down for a majority of its life. Its fate was sealed in 1966 when the Los Angeles Zoo opened about 1 mile up Crystal Springs Road. As a result, thousands of animals were transferred to the new location, the site of the old zoo was left abandoned, and you can now hike the Old Zoo trail through animal cages and even picnic inside empty exhibits (~1 mile round-trip). Further up the shaded path is an abandoned building and more animal habitats to be explored. 📍 There’s free parking near the trailhead, and the location tag will guide the way through Griffith Park. ⚠ I don't condone trespassing or criminal activity. Be aware, hiking on certain sections of the abandoned site is considered trespassing; nevertheless you’ll often find many visitors exploring the "off limits" areas.
