Isle Royale is spectacular but hard to get to. If you have limited time to visit, you can take the Sea Hunter III out of Grand Portage MN for a day trip--a trip we made in July 2012. The boat sails at 8:30 AM, arriving at Windigo harbor at about 10 AM. It returns around 2 PM, so you have about four hours for hiking. You can buy lunch or snacks at the concession store at Windigo, but we packed a lunch so that we could start hiking immediately. Moving at a moderate pace, we had enough time to hike up the Feldtmann Lake trail to reach a wonderful overlook of the lake area. There are plenty of spots on top for picnicking. If you want a shady spot, though, picnic along the bay right before beginning the climb upward. FYI, the Park Service does have a couple of simple cabins at Windigo if you want to go to Isle Royale and stay over but you choose not to camp.
