For us, a visit to the Michigan UP would have been incomplete without exploring the Soo Locks and taking a boat ride up into Lake Superior and back.
From Sault St Marie (US) our boat ride took us up into Lake Superior through a CDN lock and back to Sault St Marie via a USA lock.
The pictures below are just a miniature glimpse of our adventure.
Ships are built exclusively for transiting the Soo Locks. They are long and narrow because of the locks limited width. Iron ore is a major commodity transported through the Great Lakes.
