Welcome to the City of Cass Lake. The Cass Lake Chain of Lakes was part of the Red Lake-Leech Lake Trail, a series of interconnected waterways used as a water “highway” by Native Americans, trappers and traders. The trail ran from the southern point of Leech Lake to Cass Lake, on to Red Lake and finally to the Red River of the North. Minnesota offers the full range of resort choices, from simple log cabins in the woods to luxurious lodge suites with all the amenities and comforts of a modern hotel. The same goes for campgrounds, from rustic tent sites on remote public lands, to fully developed resort-type campgrounds with full services for RVs, and everything in between.
