Is it really haunted I'm asking because my friend lies about the paranormal stuff and he told me he heard howling in the distance

Could be after all it's in Griffith Park and some of its parts are haunted, but the animals at the zoo do make crazy sounding noises that one might perceive as ghostly 👻.

Not true..is a zoo.. ur gonna hear all kinds of noise from the animals

I used to train for marathons in those hills. I never heard anything but animal sounds.

Yes
