Dia Beacon
A former Nabisco box-printing factory turned into a vast daylit museum of large-scale contemporary art, and it works with kids far better than most art museums do because everything is enormous. Richard Serras steel spirals are rooms you walk into and get lost in, and Walter De Marias floor pieces stretch the length of a warehouse. There is nothing to read and nothing to understand, just scale and space, which lets kids react honestly. Free admission for children keeps it low risk. Ninety minutes is plenty and Beacons Main Street is right there for food.
