Isle Royale is the third-largest island (with an area of 206.73 square miles) in the contiguous United States, but you might not have heard of it. That’s probably because the people who go there often — to escape their bosses and coworkers, wander through the peaceful forests, and not have to talk about Bachelor in Paradise for once — are trying to keep its existence a secret. A narrow strip of National Park land in the middle of Lake Superior, it’s far enough away from everything that you have to take a ferry to get there, but once you do, it’s all wildlife, foot trails, and canoeing. And nobody is allowed to live there.
