It seems like there's always something to do up on the North Shore of Lake Superior. Rainy mildly cold afternoon... no problem. Go for a hike at the Temperance River Trail and hike around while you wait for the sun to show.
Best part is that with all the precip this year, all the rivers are running pretty fast and full. It was great to check this place out... right off the side of the road. Don't pass it up next time, just swing off the road and get out of the car. I think you'll be glad you did.
