Washington Crossing Historic Park preserves the Pennsylvania departure bank of George Washington's December 1776 Delaware River crossing. At McConkey's Ferry, soldiers gathered boats, artillery, and supplies for a night passage to New Jersey. Washington sought to surprise Hessian troops at Trenton after a series of American defeats and an exhausting retreat. The river, its ferries, and the road network made the operation possible. The historic park's lower and upper sections now protect buildings and land associated with the crossing and the larger eighteenth-century community, while the separately managed New Jersey state park stands across the water.

Cold weather, swift current, and floating ice complicated the movement of approximately 2,400 troops and their equipment on December 25–26. Durham boats and other craft carried infantry, horses, and cannon across; the army reached the New Jersey shore later than planned. Some supporting operations failed to cross, but the main force marched to Trenton and defeated the Hessian garrison that morning. The victory improved American morale and helped sustain the army through a critical winter. It also depended on boatmen, local ferrymen, militia, and the labor of ordinary soldiers, not a single heroic crossing.

The ferry predates the war. McConkey's Ferry Inn and other preserved buildings evoke a river corridor used for travel, trade, and household life. The Thompson-Neely property and gristmill in the upper park tell a broader story about settlement and work along the Delaware. Buildings have been repaired and interpreted over time; display boats and later commemorative features should be distinguished from surviving eighteenth-century evidence. The park's landscape includes more than the exact launch point, so directions to one building do not substitute for an understanding of the two sections and their separate visitor services.

In the days after Trenton, the army crossed and recrossed the river as both sides repositioned. Washington again confronted British forces at Trenton on January 2, 1777, and fought at Princeton the next day. These engagements changed the campaign, but they were not fought on the Pennsylvania bank. The park's annual reenactments and exhibits help explain the sequence while also showing how the crossing became an enduring national image. Preservation involves maintaining historic fabric, river views, monuments, and safe public access in a landscape used for events and recreation.

The Pennsylvania grounds can generally be visited without a ticket; individual historic building tours and Bowman's Hill Tower may require admission or advance arrangements. Schedules change by building and season, so the park's official hours and ticket pages govern a visit. The record's linked city points to Trenton, New Jersey, despite the Pennsylvania address; this reference needs correction before publication. Distinguishing the park from its New Jersey counterpart also prevents visitors from following the wrong ticket, parking, or museum advice while studying both sides of the Delaware.
