Just off of Highway 93 between Missoula and Polson. Turn west into Olson Road and stay to the right. It's about a mile in and a pullout to the right. You can drive all the way around the wetland ponds.
It's beautiful there all seasons, but I especially like the snow in the mountains and the fall colors. Although this shot was a little past the peak colors.
Ninepipe Wildlife Refuge is a wetland filled with migrating birds. This was late afternoon in November on a perfect day in Montana.
