Easily one of the highlights of the Thunder Bay area. If you are visiting earlier in the season when river levels are still high, don't miss the 40 min drive south of the city to see this one. Park in the Welcome Centre for Ontario (this is right across the border from Minnesota). Follow the signs to find the falls. You will have to follow a trail that walks back north in a shallow gully beside the highway. Cross under the road via the tunnel, and then keep left. There are two trails to the top. The one to the left gives you more views of the river on the way.
