An exceptionally rare opportunity to own what may be one of the last undeveloped, level, deep-water building lots remaining on the Grasse River and St. Lawrence River corridor. This 5.05-acre waterfront parcel is being offered for the first time as a standalone building lot, having remained part of a privately owned 210-acre family property since the early 1980s. What truly sets this property apart is its location. In less than five minutes by boat, you can leave your dock and be on the open waters of the St. Lawrence River. The entire route is through approximately 15–20 feet of navigable water, providing easy access for larger boats and eliminating many of the shallow-water concerns common to riverfront properties.
