Official Park Map
Below is the official park map provided by the National Park Service. You can view either the original PDF file or a simple JPEG image file (some of these files can be quite large). Note that while this map is useful for general navigation around the park, if you plan to do any hiking, you should really have a proper Isle Royale Trail Map.
