Washington slept here, on what is now known as the Middlebrook Trail. Most famously, while the Continental Army was bunked down here on June 14, 1777, Betsey Ross’s flag made its debut and flew over Washington and his army at The Middlebrook Winter Encampment.
The Washington Camp Ground Association holds a commemorative ceremony every July 4 near the eastern end of the trail.
Middlebrook Trail is popular with hikers and birdwatchers and especially with Eagle Scouts, whose projects help improve the area.
For other outdoor pursuits, Duke Island Park, on the Raritan Power Canal, is where you’ll find softball fields, short walking trails and playgrounds.
A popular summer concert series – with everything from blues to bluegrass – is held every Sunday.
