Minnesota is second growth country, with tiny islands of old growth you have to seek out to discover what has been lost due to statewide industrial logging. Even Voyageurs National Park is mostly second growth, marked with “sentinel trees” left on the horizon so loggers didn’t lose their way in the stumpy moonscape. But you can find examples of the various forests that used to cover the state if you are willing to travel. The DNR has a list of some sites, though they leave out a couple near Duluth, including Park Point.
Park Point old growth
The path through the park is a couple miles long but flat, an easy walk, with the Lake to the left and the bay to the right. Keep an eye out for the small poison ivy plants in the sand dunes and you should be fine.
