A rare offering on Maine's easternmost edge, this 1.17-acre riverfront estate presents a unique blend of natural beauty, privacy, and long-term potential.Imagine mornings filled with birdsong and mist rising over the St. Croix River. Afternoons spent watching seals while eagles glide overhead. Evenings on the deck, drink in hand, overlooking the nearby Canadian shore & the historic Saint Croix Island International Historic Site., the 6 acre island that was the site of an early attempt at French colonization.This is more than a property....it's a way of life.This unique riverfront escape is where nature, serenity, and potential come together. Flanked by US Route 1 on one side and the St. Croix River on the other, the land offers both easy access and a true sense of seclusion. A long drive leads to a vintage 1960s cottage nestled at the water's edge, modest in scale but rich in charm and character. Inside you'll find a cozy one-bedroom layout with a full bath, small kitchen, and living area that opens to a spacious deck with commanding river views.
