The Jacques Cousteau National Estuarine Research Reserve, designated in 1998, preserves a remarkably intact estuarine landscape where the Mullica River meets Great Bay in southern New Jersey. As one of the least disturbed estuaries in the densely populated Northeast, with less than one percent of its surroundings altered by development, it offers an exceptionally pristine coastal sanctuary. Part of NOAA's National Estuarine Research Reserve System and managed daily by Rutgers University, this reserve uniquely bears the name of an individual, honoring the renowned ocean explorer. Its salt marshes, tidal creeks, and upland woods provide a living laboratory and quiet retreat.
Best season — Spring and fall migrations bring peak bird diversity; summer offers warm paddling and active marsh wildlife; winter reveals serene, wind-swept landscapes.
