County Line Lake sits in Ontonagon County in Michigan's western Upper Peninsula — its name suggests it straddles or borders a county line, which is common for lakes in this remote, heavily forested region. With just one launch and only a handful of Google reviews, this is a quiet, lightly used lake that flies well under the radar. The nearby Sylvania Wilderness and Sylvania Campground place it in the orbit of the Ottawa National Forest, one of the most pristine and undeveloped areas in the state.
Reviewers describe it as "soooo peaceful" — and that tracks for a small western UP lake with minimal development. If you're looking for solitude, wildlife, and water that hasn't been churned up by weekend jet ski traffic, County Line Lake delivers. The Sylvania Wilderness area nearby offers some of the clearest, most untouched lakes in Michigan, and County Line Lake shares that same remote character.
