Grand Island is located of the shore of Munising Bay about 45 minutes drive from Marquette. When the weather and ice conditions are right one can hike across the the frozen bay to the south shore of Grand Island.  This side of the island is marked by steep cliffs raising straight out of Lake Superior. In the fall and early winter rain and snow melt form a long row of seemingly endless froze waterfalls. One can just cross the bay and return or make a day of it, bring a picnic, and hike across the island (only when ice condition allow it).  It takes about 30 minutes to cross the bay one way and then add however long of time one wants to spend out there. This "expedition" is easily doable with children. (We have not had a customer with disability yet, but we are confident we can make this tour possible). The crossing is accomplished either with snowshoes or cross-country skies.
