@X213G -- Becoming a member of the L.A. Zoo is definitely the best way to familiarize yourself with its collection. The zoo's website usually has a discount code for new members and you will get free admission for twelve months after you join (even into 2026). You can also get discounted admission into a variety of other zoos (more information is available on the website).
As far as being more of a zoo enthusiast in general, I've found the posts by one of ZooChat's members,
@snowleopard, to be greatly informative and inspiring. He has been to over 600 zoos all around the world and has posted many travel threads on this site. It's very interesting to compare the L.A. Zoo's exhibits to others around the U.S. and in different countries. Here's a link to his current thread on Asian zoos:
