Thousand Islands Essentials

The Thousand Islands region spans the St. Lawrence River between New York and Ontario, characterized by historic landmarks and extensive parklands. This collection features Boldt Castle, a 120-room Rhineland-style mansion on Heart Island, and the 1000 Islands Tower, which provides panoramic views from 400 feet above the river. Natural sites include Wellesley Island State Park, offering over 2,600 acres of protected landscape, and the solar-powered Sunken Rock Light. Maritime exploration is central to the area, accessible via Wolfe Island’s ferry links and regional boat tours.
