This is a great place to take the family on a nice day, as you will be in for a long day of walking. There aren't many indoor exhibits, but they have a large variety of animals. With the new Panda cubs, as well as the Cheetah Cubs, there is a lot going on at the National Zoo. The great thing is since it is the National Zoo there is no admission fee. I will admit the shape of the zoo itself is not very convenient, It is not a full circle route that you could take, as there is only one walk in entrance and so when you finish walking the zoo, you have double back to the exit, or to the parking lot where you parked your car.
