The remains are super interesting to explore, especially for kids. Unfortunately, they can become overcome with graffiti, but the city seems to do their best to keep the area clean. Every time I have visited there are families, birthday parties, and usually someone filming or photographing the area. Once you head past all the enclosures you can make your way up to the lower zoo trail which will take you above the remains and into a view of the picnic area. If you want a longer trip you can also head up to the upper zoo trail or to Bee Rock! Otherwise after making your way back down the area is lovely to set up a picnic or to play with your little ones in the grass.
Distance: approx .5 miles, with options to extend
Parking: Use “Spring Canyon Griffith Park” in the GPS application of your choice. This will take you to the parking lot right near the trailhead that gets you to the old zoo! You can also type in “Old Los Angeles Zoo” and google maps will likely take you to the same parking spot.
