Soo Locks, Sault Ste. Marie - Under the Radar

Located in Sault Ste. Marie, marvel at one of engineering’s greatest feats as giant ships from around the world make their way through one of the world’s busiest ports. Joining Lake Huron and Lake Superior, ships rise and fall 21 feet to continue their journey.


The Soo Locks have been referred to as one of the great wonders of the world and are still the largest & one of the busiest waterway traffic systems on earth! Watching huge vessels pass through the Locks is a unique experience that cannot be seen anywhere else in the United States! The Locks consist of two canals and four locks that allow vessels of many types/sizes to safely traverse the 21-foot drop in elevation of the St. Mary’s River between Lake Superior and Lakes Michigan and Huron. From viewing decks, you can watch "Lakers" and "Salties" (ocean-going vessels) as they travel the seaway between ports and navigate the rise/drop of the water levels. The Soo Locks Park Visitors Center, open from 9am - 9pm mid-May thru mid-October each year. We also have schedules of arriving vessels along with general information.
