See some of the largest seagoing vessels at the northeastern edge of the UP.

No matter that Sault Ste. Marie is a two-day drive from the Atlantic Ocean - this community on the northeastern edge of Michigan's Upper Peninsula is one of the best places in the world to get an up-close look at giant, seagoing ships.

Up to 100 ships a day inch through the Soo Locks, which bypass rapids along the St. Marys River and link Lakes Superior and Huron. During the summer navigation season, giant ore boats and freighters from far-flung ocean ports share the dual locks with commercial fishing boats and a fleet of pleasure craft. In all, nearly 10,000 craft pass through the locks each year.

From a viewing platform, you can watch ships slip through the locks, as they've been doing since 1855. Or get the insider's view when you take a narrated cruise through the locks.
