I was there about 33 years ago but that was before backpacking days. We (newlywed wife and I) stayed at one of the cabins and day hiked. We canoed across Tobin harbor and up hiked up to the overlooked on the ridge. That was great. Would love to get back for some real hiking. I doubt it is as difficult as the official advice suggests. The trails and campgrounds in the central part of the island form a network so many loops can be planed. Down south there are long linear trails. There are also a number dead end trails that offer isolated campgrounds on out and back hikes. I did backpack pictured rocks a couple of years ago. There is nothing quite like Lake Superior.
