The St. Croix River is located in northeastern Maine and forms much of the Canadian/United States border between Maine and New Brunswick. The river offers some excellent paddling trips that vary in distance and difficulty. This section starts at a public access on Loon Lake and covers 20 miles of waterway that travels through undeveloped forest terrain. The majority of this run is flatwater but there are a few small sections of class I-II rapids. There is also a portage around Kellyland Dam on the right.
