Report a Concern You are here Home About Allendale With a population of just over 6,800, Allendale prides itself on being one of the friendliest towns in Bergen County. In addition to our award winning schools, Allendale has all the charm of small town America. Our Main Street looks like a Norman Rockwell painting and the open space of our town makes it truly unique in the most populated County in New Jersey. The “gems” of Allendale include The Celery Farm, which consists of over 107 acres of preserve and is one of the most unique bird sanctuaries in the state, and Crestwood Lake Park, which hosts one of the most picturesque swim clubs in our county. Above all, what makes Allendale a great place to live is its residents. Allendale has never lost its sense of history and strives to maintain a lifestyle that is reminiscent of times gone by. Memorial Day parades, hot dogs at the volunteer fire house and fireworks on the Fourth of July all reflect the small town ambiance that is so rare.
