I did a fair amount of hiking in California before moving to Oahu, but it wasn't until I was living on the islands that I first heard of the Old LA Zoo Hike. I'm not exactly sure how I first heard of it, I'm pretty sure I came across it while doing some research on the abandoned zoo on Oahu. However, no matter how I came across it, as soon as I heard about it, and saw the pictures, I knew I had to go.
