Nomahegan Park is a 70-acre public park managed by the Union County Parks system, anchored by the man-made Nomahegan Lake. The grounds feature a mix of paved and natural walking trails that loop around the water and connect to the neighboring Unami Park. Sports facilities include multiple softball fields, baseball diamonds, and a soccer field. The park serves as a hub for local outdoor recreation, including seasonal catch-and-release fishing in the lake. A significant portion of the park is maintained as open lawn space, suitable for informal picnicking and community events. The terrain is largely flat, making it accessible for casual walkers and strollers. It provides a green buffer between the residential sections of Cranford and the nearby Union County College campus.
The pedestrian bridge overlooking Nomahegan Lake provides the clearest view of the water and surrounding greenery.
Bring binoculars if you enjoy birdwatching, as the lake attracts local waterfowl throughout the year.

Do not attempt to swim in Nomahegan Lake, as it is prohibited and monitored for water quality safety.
