We stay here when we want to go to Duluth, but don't want a hotel. It is a large campground, with sites of all types and sizes. Many sites are more private than others. Spirit Mountain Ski has many activities, right across the street. There are discounts for campers. Activities (summer) include alpine slide, zip line, and chair lift (for views of the harbor and Duluth below).
The camprgounds best features include immediate access to the Superior Hiking Trail, and an awesome mountain bike course/trail system. I prefer the walk-in sites, just for more woods. But site J was not private, and was not flat. Tent pads are small. Still, great time, and good night campfires!!! Bring your mountain bike!
