About this map

The northeastern tip of Isle Royale National Park is defined here by a series of long, parallel ridges and deep inlets, where the Greenstone Trail follows the high ground above Duncan Bay. At the center of the park's visitor activity, Rock Harbor Lodge and Snug Harbor provide a focal point for the maritime landscape of Houghton County.
