Welcome to Thousand Island

Are there really 1000 islands in New York’s Thousand Island-Seaway region? Yes, and more! Dotting the St. Lawrence River, the islands - some being no bigger than a pile of rocks - offer endless adventure! But how can you possibly see 1000 islands in one trip? An Uncle Sam Boat Tour is a great place to start, offering beautiful views of the St. Lawrence River and islands. After the tour, take a boat to the astonishing 120 rooms of Boldt Castle on Heart Island in Alexandria Bay, built for millionaire George C. Boldt’s wife, Louise. The nearby village of Clayton offers fascinating museums like the Thousand Island Museum and the Antique Boat Museum, featuring preserved North American watercraft. There really are 1000 reasons to visit New York’s Thousand Island-Seaway region!
