Boldt Castle and Two Nation Tour

Explore the beauty of the 1000 Islands on our Boldt Castle Tour

Enjoy an intimate boat tour as we travel over 27 unique miles through US and Canadian waters 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. View magnificent million-dollar homes, travel under American and Canadian spans of the 1000 Island Bridge System, and pass Rock Island Lighthouse on Rock Island.

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 as we travel through “Millionaire’s Row” and the St. Lawrence Seaway shipping channel with the possibility of viewing oceangoing vessels that travel from around the world to the Great Lakes of North America. Our small boats provide for a personal experience with our Captain and Crew. Each of our crew members have a unique, never recorded presentation, and a love of sharing the River with guests.
