"The Allagash Wilderness Waterway flows through an expansive, underdeveloped part of the state and boasts moose, bears, and blueberries along the way. For a full, multiday trip, put in at Churchill Dam and float till you reach Allagash Village, a section that has Class II rapids, lakes, and a short but mandatory portage around the Allagash Falls (well worth the effort). You'll need to register before you put in and be prepared to pay camping fees." - Travel + Leisure Editors
