Diggerland USA is the only construction themed adventure park in North America where children and families can drive, ride and operate actual machinery. The park, which covers about 14 acres in West Berlin, New Jersey (20 minutes from Philadelphia), is comprised of over 25 attractions. The majority of which are real, diesel powered, full-size, pieces of construction equipment. Each machine has undergone advanced engineering modifications which make them safe for the public, allowing children as small as 36″ to operate with little to no instruction.
