A remarkable place: 4 attractions all very high standard - Natural History Museum, Botanical Gardens, Children's Farm and Wildlife Center (which is a good size indoor zoo). If to walk through all attractions with attention to detail, it will take really the whole day. We've been there a few times.
An insufficiently rated place. It's a nice zoo. There is no such gigantism as in Dubai, less pathos. That's what I liked. We got there by taxi, also by taxi, and asked to call the staff at the entrance.
