I know that this a world famous zoo but honestly the southern boulevard entrance and a number of exhibits were difficult to find (even with a zoo map) and some exhibits were even disappointing (e.g. the small...for that size zoo... butterfly gardens and the constant pacing tiger). Be prepared to do lots and lots and lots of walking up and down gentle (not some not so gentle) hills. Additionally be prepared to wait 10 to 20 minutes for shuttles and the monorail (unless u happen to luck out...we didn't). The animals and exhibits were good mostly but a lot of effort was spent to see them.
