Washington Crossing State Park protects the New Jersey bank of the Delaware River near the place where George Washington's army landed during the night of December 25–26, 1776. The crossing began on the Pennsylvania side at McConkey's Ferry and continued toward Johnson's Ferry on the New Jersey shore. Severe cold, river ice, darkness, and the movement of artillery and horses delayed the operation. The park's roads, river views, and preserved terrain help visitors understand the geography of a military movement that is often reduced to a single image of Washington in a boat.

The army had suffered defeat in New York and retreated across New Jersey in 1776. Enlistments were about to expire and morale was low. Washington planned a surprise attack on the Hessian garrison in Trenton, using the crossing to move troops from relative safety across the river and toward the town before dawn. Other planned crossings encountered difficulties; the main force reached New Jersey later than intended. The attack on December 26 nevertheless succeeded, capturing many Hessian troops and bolstering the American cause at a precarious moment. Success depended on local knowledge, boats, ferrymen, soldiers, and coordinated marching as well as leadership.

The Johnson Ferry House stands within the New Jersey park as evidence of the river economy that existed before the battlefield became a memorial. Ferries connected farms, roads, markets, and families across the Delaware. The house's association with the crossing must be read beside that longer use of the property. The soldiers who landed here did not fight a set-piece battle on the riverbank: they marched toward Trenton after completing the crossing. Later campaigns at Trenton and Princeton built on this operation, but their battlefields occupy different places. The Pennsylvania park across the river preserves the departure side and is a separate institution.

New Jersey established and developed its state park to protect the crossing landscape and support education and recreation. Interpretive facilities, trails, monuments, and programs have changed the appearance of the landing area. Vegetation, roads, and river conditions today cannot recreate the exact weather or shoreline of 1776. The site's value lies in the surviving topography and its relation to the river route. The Johnson Ferry House and museum offerings add context where available, while open grounds allow visitors to trace the approach to the crossing and the army's route toward Trenton.

The state lists no general park entrance fee and posts gate hours separately from office or museum hours. In 2026 work on a new visitor center affects parts of the grounds, and visitors must stay out of construction areas. The main park entrance on Washington Crossing–Pennington Road remains in use. Park alerts also note temporary restroom arrangements. These practical details matter because older descriptions have incorrectly suggested a day-use entrance charge or assumed that every interpretive building is open. The park should be described as the New Jersey landing landscape, with its access conditions kept distinct from those of Washington Crossing Historic Park in Pennsylvania.
