There are several state parks along highway 61 going up the North Shore, however, if you want full hookups you have limited choices.
Burlington Bay Campground, the city park in Two Harbors.
The City of Grand Marais Rec Park, in Grand Marais.
The Grand Portage Casino campground in Grand Portage.
That's it!
The area is beautiful and well worth the trip. Both Two Harbors and Grand Marais are nice towns with stuff to see and do. Both city campgrounds are right on Lake Superior, and within walking distance to town.
Grand Portage is pretty far up, and there's not a lot to do there IMHO, except a National Historic Site that's nice.
