I Kayaked out to the Slate Islands on July 5 and camped on Patterson island for 5 nights at 3 different site. There are no actual backpacking trails on the islands other than one that leads up to the lighthouse, but there are some "breadcrumb" trails that were left by caribou counters several years ago. My son and I had fun looking for the orange tags tied to tree branches from the old barge camping site that leads back to mud lake. It is actually bushwacking due to the incredible deadfall and new growth of the pine trees. There was also swampy areas as we aproached the lake which did not have very good footing, so trekking poles are a necessity! We also kayaked around Patterson island on a beautiful calm sunny day, which was spectacular! We made the trip in 6 hours which included a one hour stop-over at the lighthouse for viewing and lunch. I would not call this group of islands a trail spot, but if you want solitude, good orienteering opportunities, great wildlife, (woodland caribou, bald eagles, loons, fox, wolves, etc) this is the place! Oh yes, we did hear wolves howling at night, I don't care what the Ontario Ministry of Natural Resources says!
