Overview

The tour departs from Clayton, New York, and lasts about three and a half hours. It begins with a guided boat cruise along the St. Lawrence River through the Thousand Islands region, covering over 27 miles. The boat travels through both U.S. and Canadian waters without requiring a passport. Passengers will see numerous islands, waterfront mansions along the well-known "Millionaire's Row," and pass under both spans of the Thousand Islands Bridge System - one in the United States and one in Canada. The route circumnavigates Wellesley Island, the largest U.S. island in the area, before continuing north through Canadian waters to Heart Island. On Heart Island, passengers have approximately 75 minutes for a self-guided visit to Boldt Castle and the Boldt Yacht House. The boat includes onboard restrooms, and a local naturalist guide provides commentary throughout the tour. Along the way, the tour offers views of landmarks such as Rock Island Lighthouse State Park, Thousand Islands Park, and waterfront areas in Clayton, New York, and Rockport, Ontario. Entrance fees to Boldt Castle are not included but can be purchased at the ticket booth upon arrival or reserved in advance. Picnic lunches are available for pre-order but are not included. The tour covers the two nations of the United States and Canada, providing detailed information about the islands and the surrounding region.
