![]() NPS photo Snowmobiles are permitted on unplowed park roads used by motorists in summer, as well as the frozen waters of Lake Superior and Grand Sable Lake. These unplowed roads (and the shoulders of plowed park roads) are open to snowmobiling in conformance with state law. Snowmobiles are prohibited from cross-country travel and travelling on park trails (off road/trail travel). In other words: with the exception of trails listed below, snowmobiles are not permitted where motor vehicles are not allowed in summer.
