I would say this is a good day out but be prepared not to see a lot of animals in every enclosure as they hide away from view. Unfortunately our visit was overrun by huge numbers of school kids who ran around screaming while their teachers either ignored or shouted at them. Even some keepers were complaining, I'd recommend going in the school holidays as the parents with kids kept theirs under control!! It's a big zoo so expect to spend at least 4 hours looking around.
