Much like the Great Lakes themselves, the Soo Locks are vital to Sault Ste. Marie’s tourism industry. The Soo Locks sit at the northern end of the St. Marys River connecting Lake Superior and Lake Huron. The Locks make it possible for boats, of all sizes, to traverse the 21-foot difference between the upper river and the lower river better known as the St. Marys Rapids. Locking through is your opportunity to experience the tour boat raising, or lowering, with 22 million gallons of water fed by gravity (no pumps) into the Poe Lock.

With a bit of luck, you’ll be able to pass by a freighter and get a real understanding of their incredible size and powerful presence on the river. The Famous Soo Locks Boat Tours and Original Soo Locks Boat Tours offer an experience to remember. You will ride through the Soo Locks, share the river with freighters and other vessels, and perhaps spot some wildlife! It’s a maritime adventure that’s educational, lots of fun, and you don’t need a passport.
