We took our almost 2-yr old son to the park. We have been to the Reston Zoo before. The facility is not as nice as the Reston Zoo but they are very similar. Lots of small animals for kids to see and feed, many of which I cannot name. They do have the standard animals like turtles, camels, horses, pigs, goats, donkeys, chickens that roam around and hang out with other animals. I didn't see sinks for washing hands but there were a few hand sanitizer dispenser. The entire place is outdoor except the little half open gift shop and the little hut which is the ticketing office, so pick a day when it's not likely to rain. There's a little playground area and a moon bounce as well. The wagon ride was pretty boring. Half of the times we could not hear the guide and my son was not too interested being confined in the trailer. Other than that he had a good time.
