Capital Children's Museum
800 3rd Street NE, Washington D.C.
Once there, this is a great destination for grandparents and children. Kids can
participate in the numerous activities without too much strain on their parents and
grandparents. However, if you are concerned about preserving your energy, take the short
cab ride from Union Station. The blocks to the Capital Children's Museum are rather long
and aren't paved well.
Go in the mornings when it is less crowded and let the kids work up an appetite. Then
go to Union Station for lunch.
