3.5 Hours | A unique tour of Boldt Castle & Two-Nation


Join us for the most unique and complete Boldt Castle/Two Nation Tour experience. Enjoy an intimate boat tour as we travel over 22 unique miles among many of the 1000 Islands along the St. Lawrence River. We begin in Clayton miles south of Boldt Castle, travel up the American Channel of the St. Lawrence Seaway. Our professional guides will share rich history, legends and lore as we get you up close to the islands allowing adults and children the ability to spot local wildlife.

This international tour will include views of Magnificent Million Dollar Summer Homes on both the US and Canadian shorelines, travel under both the American and Canadian spans of the 1000 Island Bridge System, and pass Rock Island Lightouse State Park.

At Heart Island you have the option to disembark and enjoy a self-guided tour of Boldt Castle.

Returning to Clayton through the Canadian Channel of the St. Lawrence River, we will travel by the smallest international bridge, through the whirlpools of “the lost channel,” pass by Tom Thumb Island, the Statue of St. Lawrence, through Eel Bay, and wind through the islands in front of Clayton, the real Heart of the Thousand Islands.
