If you go up the North Shore in Minnesota, the best shore dive is the Madeira. You'll have to stop and get the combo to the gate, and a State Park pass.
Split Rock Lighthouse
The lot is spacious on weekdays and reserved for divers only. (hence the gate combo)
The trail down to the lake isn't to tough but you might want to carry the tank down before you suit up. There is a swim out to the wreck then but it isn't too bad, or you could take a direction and hit the bottom.
This looks farther than it is.
