The Soo Locks is one of the most well-known historical sites in Michigan’s Upper Peninsula. Connecting two Great Lakes—Superior and Huron—the Soo Locks were first constructed in 1855 and have served as the ‘Linchpin of the Great Lakes’ ever since.

The largest freighters on the Great Lakes, along with tall ships, sailboats, cruise ships, and military crafts, all traverse the Soo Locks, moving from one lake to another. An observation platform overlooking the MacArthur Lock provides an up-close view of the mammoth freighters and unique vessels passing by.

Soo Locks Park offers excellent views of the historic locks too. Just a few steps from the water’s edge, the park features shady grass, walkways, gardens, and trees typical of Michigan’s Upper Peninsula. Additionally, on the grounds stands the historic 1899 US Weather Bureau Building. Open year-round, this building hosts a public exhibit, a museum store, and access to the Shipwreck Society’s noted Great Lakes Images and Papers Collection.
