Uncle Sam Boat Tours

One side of the St. Lawrence River is the U.S., the other is Canada. Why choose?

We’ll save you the counting: There are actually 1,864 islands in the Thousand Islands, and no, you can’t visit them all. But you can see a lot of them from a tour boat. One of the most well-established operators, Uncle Sam Boat Tours, offers a popular 2 ¼-hour, two-nation trip that cruises both American and Canadian waters. Lunch and dinner tours, twilight cruises and other packages available. (And if you’re wondering … if it stays above water all year long and can support at least a single living tree, it counts as an island.)
