Celbridge, Ireland

Celbridge may look picturesque, but don't be fooled - this commuter town is no idyllic retreat. With a population of over 20,600, it's the third largest in County Kildare, and growing rapidly. While the 18th-century architecture has charm, the town's expansion has created persistent traffic congestion. And bureaucracy is a headache, with Celbridge lacking its own town council, leaving zoning decisions to the county. Still, the proximity to Dublin and array of schools make Celbridge an appealing option for young families seeking more space, if they can tolerate the hassles.
