The 25-mile Millstone Valley Scenic Byway is situated in central New Jersey, largely in Somerset County, but also in small portions of Mercer and Middlesex counties. The historic Delaware and Raritan Canal runs through most of the Byway with Canal Road on one side and River Road on the other. It was designated a New Jersey Scenic Byway in 2001 and it became one of two New Jersey Scenic Byways that were nationally designated in 2009.

The long and narrow Millstone Valley is the flood plain of the Millstone River and its many tributaries. It is a scenic area settled by Europeans in the late 1600s and early 1700s and was home to the Lenni Lenape people before settlers arrived. The river served as an early means of transportation as did Indian trails, which both paralleled and crossed the river. These trails later became the roadway system for this area, including Canal Road and River Road which comprise the core of the Byway. The land between Canal and River Roads is now part of the Delaware and Raritan Canal State Park. The Millstone Valley Scenic Byway Visitor Center is located in the Griggstown Bridgetender's House and is open weekends to the public from April to October.

The Millstone Valley’s historic qualities are regionally and nationally significant especially for those historic periods representing the Revolutionary War, Early Dutch and American Heritage, and the Canal Era.
