The Upper Raritan River Watershed is home to a network of diverse preserves and natural areas. These lands are managed to protect critical water sources, provide wildlife corridors, and offer community space for nature study and reflection.

Raritan Headwaters owns and maintains 9 preserves and natural areas within our watershed. All are open to the public, though amenities like trails and river access differ from place to place. These preserved lands protect water quality in rivers and streams, safeguard wildlife habitats, filter pollutants from the air and maintain the rural character of our communities.
