Soo Locks, Sault Ste. Marie

4.6
#1 of 11 in Things to do in Sault Ste. Marie
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.

  • What a hoot to see a freighter pass thru. Been to da Soo plenty of time for college hockey but this is the first time here that the locks were still open. Once you get boatnerd.com go to vessel passag...  more »
  • The locks are fun to observe ships coming in, the raising of the water and then the ships moving out. Very nice viewing platforms and nice park surrounding the locks. Clean and for October the weather...  more »

  • See the locks from the viewing station and check out the visitor's center while there. It's filled with fascinating info. Then ride the locks ink the Soo boat tour. A nice little tour of the locks and the river, and the captain provides an informative narration throughout. I wouldn't recommend bringing young children. The few I saw were clearly bored. However, it's a fascinating engineering marvel for those older enough to appreciate it.
  • It's hit or miss on if a boat will be going through at the time you will be there unless you do some homework. AFTER 6PM THE PARKING METERS ARE FREE. We did not read them and put in a quarter before someone pointed this out too us lol.
  • Pretty cool watching the ships pass!! Cool little walkway that has signs with history info on them!
  • Great place to sit and watch freighters go thorough the locks. If you go on Engineering Day you can walk across the Locks and see the post office in the middle of the locks.
  • It's pretty and very unique.. no boats when I was there but it's really I sight to see and many areas to walk around. Totally worth it
