The 25-mile Millstone River 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.

Visitors should take some time to enjoy the South Riverwalk Park located on top of the tunnel and include an event at the Trenton Thunder Arm and Hammer Park located just north of the tunnel in Waterfront Park.

The State Capitol, visible from Route 29, offers guided tours that are approximately an hour in length Monday through Friday on the hour from 10 am to 3 pm. Within walking distance visitors can also spend time at the New Jersey State Museum, the Planetarium, the State Library and the Old Barracks.

North of Trenton, Route 29 offers impressive views of the Delaware River. Three outstanding state parks are located along the Byway. The Delaware and Raritan Canal State Park offers a 30-mile bicycling and walking trail, nine fishing and boating access areas to the Delaware River, and the historic site of Prallsville Mills located in Stockton; Washington Crossing State Park commemorates a pivotal event in the nation's revolutionary war history and is located directly adjacent to the Washington Crossing Bridge; and Bull's Island Recreation Area is a forested island in the Delaware River with access to Pennsylvania by a historic steel suspension pedestrian bridge.

Visitors to the area have many venues to appreciate the historic, cultural and recreational features of this region in city, town and countryside settings. Mercer County Park Commission offers views into the past at the Howell Living History Farm. The Holcombe-Jimison Farmstead Museum is dedicated to the preservation of Hunterdon County's 18th, 19th and early 20th century cultural and agricultural heritage.
