The Assunpink Creek is a 22.9-mile long tributary of the Delaware River in western New Jersey. It originates in Monmouth County and flows generally westward through Mercer County before emptying into the Delaware River in Trenton. The creek's name comes from the Lenape term Ahs��n'pink, meaning stony, watery place.

Paddling opportunities on the Assunpink Creek are primarily concentrated in two areas: the Lower Assunpink Creek section near Trenton and Assunpink Lake in Upper Freehold. The Lower Assunpink offers about 5 miles of flatwater paddling with tidal influence as it flows through a mix of wooded areas and marshlands in downtown Trenton. Assunpink Lake, located in the Assunpink Wildlife Management Area, provides a mile-long flatwater paddling experience popular with anglers.

The overall difficulty of paddling the Assunpink Creek ranges from easy to moderate, suitable for beginners to intermediate paddlers. The lower section near Trenton requires some navigation skills due to tidal influences. Spring and fall are ideal paddling seasons, offering comfortable temperatures and adequate water levels. Summer paddling is possible but may require more portaging in shallow areas.

The creek and surrounding areas support diverse wildlife, including beavers, various fish species, and numerous bird species. Anglers frequent Assunpink Lake for its excellent largemouth bass fishing, with trophy-sized catches over 5 pounds common. Other popular fish include pickerel, crappie, and panfish.

Key landmarks include the 500-foot buried concrete culvert section in downtown Trenton, old bridges crossing the creek, and the scenic Assunpink Wildlife Management Area. Old York Road in Trenton for the lower section and the Assunpink Lake boat ramp in Upper Freehold serve as access points.

Historically, the Assunpink Creek played a role in the American Revolution, with a notable battle fought along its banks in Trenton in 1777. Today, it serves as an important recreational resource for the region.

Safety considerations include being aware of tidal influences in the lower section, watching for submerged obstacles, and respecting hunting seasons in surrounding areas. A New Jersey Boat Ramp Maintenance Permit is required to launch at Assunpink Lake.

While multi-day trips are not common on the Assunpink Creek itself, paddlers can combine a creek excursion with exploration of nearby Stone Tavern Lake and Rising Sun Lake for a longer adventure in the Assunpink Wildlife Management Area.
