Beginning in the 1900s, people came from New York city and Jersey City to get fresh country air in the then-rural Wyckoff. There were boarding houses like the Stafford, Harold House, and the Grove Villa. Some of the early social activities were church picnics, baseball games on Zabriskie and Appert Fields, soapbox derby races down Clinton Avenue, swimming in several swimming holes in town, and Saturday night dances at the Grange.

The Fire Department was one of the first community organizations formed. A fire in 1905 destroyed 24 outbuildings on the Ewing Estate (now Franklin Lakes). Several residents decided that the town must have a fire department. Early founders were Charles Parmley, Daniel DePew, Valentine Goetz, James Winters, and the Reverand Strohauer. Today, there is still a great sense of volunteerism in Wyckoff.

The Police force was created in 1922. The first Chiefs of Police were Albert Holtz, Thomas Young, James Morrison, and George Gallant.

Even though Wyckoff grew slowly in the early years, the post-World War II period demonstrated growth that added many nicely designed housing developments and single-family homes that seem to have filled every open space. The town today is a mature suburban area.

The Memorial Day Parade is an important townwide event that is held every year. Spring Lake and the YMCA continue to be a source of activity for the town.
