Phoenix zoo is not too big, easily-walkable and visitor friendly. Just you need 2.5 to 3 hours to tour the whole zoo and it has animals such as orangutans, baboons, giraffes and zebras. A narrated Safari train tour is available daily and you can enjoy that too by taking photographs. As well as
Sedona,
Phoenix has lot to offer, so explore it and enjoy the
Arizona tour. Best of luck!
