Mahwah is the northernmost and largest municipality by geographic area (26.19 square miles (67.8 km2)) in Bergen County, in the U.S. state of New Jersey. As of the 2020 United States census, the township's population was 25,487, a decrease of 403 (−1.6%) from the 2010 census count of 25,890, which in turn reflected an increase of 1,828 (+7.6%) from the 24,062 counted in the 2000 census. The name "Mahwah" is derived from the Lenape language word "mawewi" which means "Meeting Place" or "Place Where Paths Meet".The area that is now Mahwah was originally formed as Hohokus Township on April 9, 1849, from portions of the former Franklin Township (now Wyckoff). While known as Hohokus Township, territory was taken to form Orvil Township (on January 1, 1886; remainder of township is now Waldwick), Allendale (November 10, 1894), Upper Saddle River (November 22, 1894), and Ramsey (March 10, 1908). On November 7, 1944, the area was incorporated by an act of the New Jersey Legislature as the Township of Mahwah, based on the results of a referendum held that day, replacing Hohokus Township. New Jersey Monthly magazine ranked Mahwah as its ninth best place to live in its 2008 rankings of the "Best Places To Live" in New Jersey.

The park offers hiking along a mountain brook with a waterfall, fishing in the Ramapo River, Scarlet Oak Pond, MacMillan Reservoir, and tent camping. Trails connect to the network of trails in the adjoining state forest and state park. The park also affords carry-in access to the Ramapo River for canoe, kayak and raft owners. The Reservation is popular among students from nearby Ramapo College, less than a mile away on Route 202, and acts as the school's Environmental Science laboratory. The park is also a noted geocaching hotspot in conjunction with the aforementioned adjoining parks.

Campgaw Mountain Reservation is a 1351-acre (5.5 km2) county park of Bergen County, New Jersey. It is located mostly within Mahwah, but extends into the northeastern part of Oakland (southwest of Glen Gray Road), as well as the northwestern part of Franklin Lakes. The park includes a ski area and the peak of Campgaw Mountain at a 735-foot (224 m) elevation.The ski area has two 2-person chairlifts and 3 magic carpet style lifts suitable for novice skiers. The first chairlift was built by HALL ski lift in 1968. Chairlift 2 was built by HALL in 1970, and features a midstation exit for skiers who do not want to go to the top of the mountain. The area also has opened up a section of the smaller hill for patrons to rent inner tubes and slide down to the bottom. There are two handle tow style lifts that drag the tube with the user in it to the starting area. The area also has a small lodge, cafeteria, snack bar, and equipment rental shop. The area is a hangout for local kids from the surrounding area. Many of the skiers are just beginning or are novices at the sport, and the mountain attracts people from the surrounding urban areas as well. It is the closest ski area to New York City. The mountain's highest trail features a vertical drop of 270 feet (82 m) over a distance of about 1,200 feet (370 m). The steepest section of this trail is the first 200 feet (61 m) downhill of the summit. The remaining 1,000 feet (300 m) or so of trail is mostly flat with a smooth decline. To the east of the park is Interstate 287. To the west of the park is U.S. Highway 202 and the Ramapo River. In 1955, the U.S. Army created a Nike Missile station there for the defense of the New York Metropolitan Area from strategic bombers. In 1959, the site was upgraded to house Nike-Hercules Missiles with increased range, speed and payload characteristics. The missile site closed in June 1971.
