Summary

Harbor Island is a fifteen-acre freehold island in the St. Lawrence River at Alexandria Bay, in the heart of New York's Thousand Islands and directly beside the landmark Boldt Castle, listed at USD 2,685,000. It arrives developed with a three-bedroom river home and protected deep-water dockage, and the listing notes subdivision potential. For a buyer, it offers an established, boatable river retreat in one of North America's most storied island archipelagos, with immediate usability rather than a build requirement.

Land & Waterfront

The island's setting is its defining asset: fifteen acres on the St. Lawrence with direct views of Boldt Castle and the constant passage of river freighters and pleasure craft. Protected deep-water dockage supports serious boating and swimming, and the Thousand Islands' cruising grounds extend in every direction. The scale and subdivision note suggest flexibility to hold privately or to create additional homesites, while the existing river home anchors immediate use.

Access & Utilities

Access is by boat from Alexandria Bay, with the island's protected deep-water dock giving reliable mooring — though the listing does not publish mainland transfer distance or a full utilities breakdown. Power, water and communications specifics are unstated, so a purchaser should confirm the servicing arrangements supporting the existing home. The cathedral-ceilinged, wraparound-porch residence and storage garage indicate a functioning setup, but the technical detail needs verification during diligence.

Ownership & Use

Tenure is freehold with no foreign-ownership restriction, keeping acquisition straightforward for international buyers. The dwelling makes it usable from day one as a private river retreat, while the noted subdivision potential offers an optional development angle for additional homesites, subject to New York and riparian permitting. Diligence should focus on confirming utilities, the condition of the home and dock, and the practical feasibility and permitting of any subdivision along the St. Lawrence frontage.
