Need proof that New Jersey is diverse? Delve into the Delaware River Region, and experience both the stereotypes and surprises of the Garden State. The region is steeped in colonial history, from the stately mansions of well-to-do Haddonfield to the agrarian adventures of Cherry Hill’s Quaker Barclay Farmstead Museum. But in both places, you needn’t go far to experience the present: top-notch shopping, fine-dining and ethnic eatries. Need a little high-brow activity? Stroll amid the Gothic buildings of Princeton and soak in the collegiate atmosphere. Enjoy New Jersey’s green side by camping, hiking and rafting through Delaware Water Gap. History buffs go nuts for the USS Battleship, kids get enthralled by Adventure Aquarium, and literary fans swoon at the Walt Whitman House. Even Camden, long plagued by urban decay, is revitalizing its waterfront district, luring tourists with its offbeat flavor and Philadelphia views. Just freeways and strip malls? We don’t think so.
