Koziar's Christmas Village is a seasonal attraction rather than a year-round sight, but in the Reading area it has enough local fame to matter. The experience is deliberately old-fashioned: paths through dense light displays, decorated buildings, holiday scenes, and plenty of families making an annual ritual of it.
Only add it to an itinerary if you are travelling in the right season and you are happy with crowds and traffic on peak nights. Outside that window it is irrelevant; inside it, it becomes one of Berks County's more distinctive evening outings.
