I like to visit local zoos whenever I travel. I am a big animal person, and I find it fasinating to see the differences between locations. The most notable are always over sees. I have been to San Diego several times on business, but this was my first leisure trip. The zoo was my only must do while I was there. It did not disappoint. They had a great selection of animals. The best was the baby panda. The layout of the zoo is very hilly, so be prepared for a nice hike if you don't take the bus and want to see everything. I love the idea of seeing animals and getting excersize. I would certain buy a season pass if I was loca. I cannot recommned this zoo enough. Do not miss it.
PS not a great zoo for small children in strollers. I would suggest taking the bus option when you have kids, but even then it may be tough.
