Old Woman Bay and other parts of Lake Superior PP. If you enjoy hiking, the Orphan Lake Trail is an especially good hike if you're up for a full day hike, Pukaskwa NP and it's many trails and both beaches are very nice. There are excellent views at some spots along the eastern shore between the Soo and Wawa. Some pretty spots after Marathon. Marathon itself is interesting, but it's challenging to get to the views.
There are some spots near Sleeping Giant where one can hunt/collect Amethyst at private mines. That can be a fun activity.
Oh, and the trading post just before Pancake Bay PP.
Conversation at that trading post some years back:
There was a foreign vendor (Indian guy) selling what the sign said were Reindeer pelts from northern Europe. My young daughter read the sign and it went like this:
Daughter (a little distressed): Reindeer Pelts??
Vendor: Yeah, reindeer pelts!
Daughter (horrified): Like Rudolph?
Vendor: Yeah yeah! Rudolph!
Had to spend some time explaining that reindeer are common in northern Europe and these weren't Santa's ...
