Collectively, these communities are known as "The Wildwoods. " The Wildwoods began developing as a resort in the last decade of the 19th century. A building boom began in the 1950s, due partially to the construction and completion of the Garden State Parkway. Wildwood is a resort city that is very popular with vacationers and tourists mostly from New Jersey, Pennsylvania, New York, Delaware and even nearby parts of Canada during the summer months.
