The William C. O'Neill Bike Path (also called the South County Bike Trail) is a paved rail trail extending from Kingston station parking lot in West Kingston, Rhode Island, to Mumford Road in Narragansett, Rhode Island. The whole path is in Washington County, Rhode Island. The trail is 6.8 miles (11 km) long, largely on the former right of way of the Narragansett Pier Railroad. An extension opened up to the University of Rhode Island in 2019. A future extension will bring it to Boston Neck Road (RI 1A).
