Boldt Castle Tour in Clayton, NY

Join us for the most unique and complete Boldt Castle and Two Nation Tour experience. Enjoy an intimate boat tour as we travel over 25 unique miles among many of the 1000 Islands along the St. Lawrence River. Our professional local guides share rich history, legends and lore as we get closer to the islands than any other tour. This international tour includes views of magnificent million-dollar homes on both the US and Canadian shorelines, travels under American and Canadian spans of the 1000 Island Bridge System and passes Rock Island Lighthouse State Park.

Departing from Clayton we travel through Canadian waters of the St. Lawrence River, by Tom Thumb Island, the smallest island, through the whirlpools of “the lost channel,” the Statue of St. Lawrence, through Eel Bay, and wind through many of the beautiful  islands. At Heart Island guests have the option to take a self guided tour of millionaire George Boldt’s Castle, built as a testament of love for his wife Louise, before tragedy struck in 1904. Marvel at life in the “Gilded Age” for the wealthy who built magnificent castles and summer homes on islands along the River.

Returning to Clayton we travel through US waters and the St. Lawrence Seaway shipping channel where we may get you close to one of the great ships, “Lakers” and “Salty’s,” that travel the St. Lawrence River and the Great Lakes. This tour completely circles Wellesley Island, the largest US Island and our boats allow for a personal experience with our Captain and Crew. Each of our guides has a unique, never recorded narration, and a love of sharing the River with guests.
