A somewhat confusing pattern to the zoo. Followed their map and still thought too many ways to go. Thank god for the 2 buses that are included in the zoo admission fee. The tram is also included, that got us to the back of the zoo twice. Some of the pens are old looking. I still feel no one can go to San Diego without going to the zoo. Give yourself a lot of time, patience and really good shoes.
