Located in Mercer County’s Roebling Memorial Park, Spring Lake is a sanctuary for both wildlife and humans. The trails here offer rich wildlife viewing opportunities to park users. Like the rest of the Abbott Marshlands, Spring Lake has been a favorite destination for people throughout its history. Beginning as an escape from the city for Trenton residents, Spring Lake provided a location for peaceful walks and boating. Its popularity fueled the development of an amusement park before being designated as a wildlife refuge.
