You might want to check the train routes. The train goes along the North Shore of Minnesota. I have taken the train to Minneapolis, but didn't try traveling north of there. I can't remember if I saw anything about passenger trains or tourist trips, but it might be a place to look. I will try to find my Minnesota brochures and let you know if I see anything. Otherwise, rent a car. You must see Split Rock and when you are there make sure that you take the walk down the hill for the wonderful view of the lighthouse on the rock. Two Harbors is also very nice. I was glad I decided to look for it. If you like waterfalls, Gooseberry Falls is a beautiful area. There are numerous waterfalls along the north shore.
