Which way to look from Grand Marais

Face north. From Grand Marais the auroral oval sits well to the north, so activity shows up as a glow low on the northern horizon rather than overhead — which means a clear, unobstructed northern view matters more here than total darkness does.

About aurora viewing in Grand Marais

Grand Marais sits directly on Lake Superior's North Shore, a stretch of coastline well known among Midwest aurora chasers for its open, north-facing water views and easy highway access compared to more remote wilderness options.

Where locals actually go

Artist's Point, a rocky outcrop right at the edge of downtown, is the classic local spot, close enough to walk to but still dark enough away from the town's small light footprint.

Best time of year

Lake-effect cloud cover off Superior can work against you here even when the geomagnetic forecast looks good, so check the sky, not just the Kp index.
