My children were 11 and 8 when we went, they call it "Chessington World of Yawn". Queues were excessive and ride selection not great. You have to go on a ride to see most of the animals so queue for an hour to catch a glimpse. The gorillas and other animals you can walk around are down a narrow pathway enclosure so you couldn't really get close to see or were just in somebody's way. Wouldn't go again there are many better theme parks and zoos.
