About aurora viewing in Copper Harbor

Copper Harbor sits at the very tip of the Keweenaw Peninsula, jutting further north into Lake Superior than almost anywhere else in the Midwest, which gives it a real magnetic-latitude edge over towns further south in Michigan.

Where locals actually go

The peninsula's remote, sparsely populated tip means dark sky is the norm rather than something to seek out; Lake Superior's open water to the north gives an unobstructed view.

Best time of year

Copper Harbor's remoteness means fewer services and longer drives than Marquette or Mackinaw City, a tradeoff for some of the darkest sky in the region.
