The San Diego zoo is really big. We went on a Sunday and it surprisingly wasn t that crowded. There is a lot of walking around from area/climate/ region which makes a day at the zoo well spent ! Make sure to take the bus as it gives you a guided tour around the path and then you can walk around areas you would like to explore more. Bring plenty of water /)
