It is possible to visit Isle Royale for a day trip using the Wenonah from Grand Portage, Minnesota or the Isle Royale Queen III from Copper Harbor, Michigan.

But to explore the backcountry, you will need to spend multiple days. Other campgrounds accessible by ferry offer day hiking possibilities as well. One could base camp at Washington Creek for 3 days, then continue on the Voyageur II to McCargoe Cove to spend another 3 days. Or do the same thing at Daisy Farm and Moskey Basin, with either a hike or a water taxi inbetween. Other such creative possibilities exist.
