This section of the Highlands Trail begins at the Roebling Bridge in the Borough of Riegelsville and follows the D&L Trail south for 5.3 miles along the Delaware Canal towpath in Delaware Canal State Park to the planned Ringing Rocks Trail. The 165-mile D&L Trail is a National Recreational Trail that is coordinated by the Delaware & Lehigh National Heritage Corridor. The entire D&L Trail along the Delaware Canal Towpath is part of the Delaware Canal State park and as such is maintained by park staff. Friends of the Delaware Canal is a non-profit organization that advocates for the protection and maintenance of the the canal and its towpath.

This section of the trail in particular contains several nationally significant historic and natural features, with outstanding views of the canal, Delaware River, preserved farmland, Nockamixon Cliffs (PA side of the river) and Milford Bluffs (NJ side of the river).

Trail access can be found at one of the small parking lots along the Delaware Canal on Rt 611 or River Road (Rt. 32). Other features along the trail include restaurants and overnight accommodations (Riegelsville Hotel, Riegelsville Inn, Indian Rock Inn), Fig Tree Deli, Borderline Cafe, and Traugers Farm Market).
