Well, growing up in the suburbs of Washington, DC, you could just not go to the zoo at least once a year. As a child, we always took field trips in school here; and as an adult, one just seemed to gravitate back to their roots here. This zoo is absolutely wonderful! It is absolutely huge...and you will definitely be tired out by the time you are done! You truly need a full day to be able to enjoy all the animal exhibits. The best thing...it is free! Yeah, you probably have to pay for parking if you can't find a spot on the street, but that's a drop in the bucket. Kids of all ages will enjoy the pandas, lions, tigers, and much, much more. A definite must see while in our Nation's capital!
