Create an itinerary including Soo Locks
See how 10,000 ships travel between Lake Superior and the lower Great Lakes every year at Soo Locks. Historically significant, the first versions of these locks were built in 1855 to accommodate a 6.4 m (21 ft) drop between Lake Superior and Lake Huron, and they still are noted for their engineering prowess. Today vessels traveling through the lock system here transport more than 86 million tons of cargo. The locks are named for the two cities on either side of the St. Marys River, one in Michigan and one in Canada. Both cities are names Sault Ste. Marie, with Sault pronounced as "Soo." The locks now make up 2.6 km (1.6 mi) of a canal that is run by the U.S. Army Corps of Engineers. Plan your Soo Locks visit and explore what else you can see and do in Sault Ste.

  • While we were there, we had a chance to see two boats go through the locks. Just what we wanted to see. The inside museum was informative also, even though we didn't have much time to browse.

  • I had a great time here. I went to the visitors center first which was very informative. From there I went to the observatory and was able to see the locks open and closed. It was amazing to see 22 million gallons of water be moved as quick as it does. I walked down to the lower area and seen the river. Walked the grounds which were very nice and maintained. NOTICE.... This IS a U.S. government installation. Save yourself some time and secure ALL weapons in your vehicle before entering the gate.
  • Soo Locks A man-made marvel and the busiest lock system in the world, by cargo tonnage, yes the Soo Locks! On average, between seven and ten thousand ships come through the locks during the shipping season each year. Built in 1855, these locks connect Lake Superior to Lake Huron and beyond. Fantastic to go through it Looks identical to the Panama Canal.. Less tech Soo much development happening.. will be great in the years to come .. A Must Visit
