Mahwah occupies the northwestern corner of Bergen County, where New Jersey meets both New York State and the Ramapo Mountains. It is the county’s largest municipality by land area and includes a mix of suburban neighborhoods, corporate campuses, shopping areas, institutional properties, and extensive wooded terrain. Routes 17 and 202, Interstate 287, and nearby New York State highways connect the township to the rest of Bergen County, Rockland County, and northern New Jersey. Ramapo College of New Jersey is located in Mahwah, and the township is also home to the Ramapo Valley County Reservation and other natural areas that provide trails and access to the Highlands landscape. Mahwah’s several historic neighborhoods and former rural settlements developed along older roads and rail lines before later suburban growth expanded across the township. The community borders Ramsey, Allendale, Wyckoff, Franklin Lakes, Oakland, and Ringwood, as well as multiple New York municipalities. Its setting combines regional accessibility with unusually large areas of open land for Bergen County.
