If they are the ones I think you're talking about? They're right where the Kawishiwi River enters Fall Lake. Just drive north up Hwy 169 through Ely a few miles, watch for signs. (If I remember right the sign says Kawishiwi Falls hiking trail????) It will be on your left. If you go past the Fall Lake campground, you've gone too far. There's a small parking lot, then a short hike to the falls.
