About aurora viewing in Bigfork

Bigfork is a small town at the northeast corner of Flathead Lake, and when the aurora appears here, it hangs low over the hills across the water, close enough that it can feel almost within reach.

Where locals actually go

The Flathead Lake shoreline right in Bigfork is the classic vantage point, with the lake providing an open, unobstructed view north without needing to drive far out of town.

Best time of year

You can't count on a Montana aurora every year, but when conditions line up, the lake's reflection makes it a distinctive show worth the wait.
