Any idea where abouts in the UP you are thinking about going? The UP is about 400 miles and an 8 hour drive from one extreme to the other. No use recommending something in Copper Harbor if you're not going any further then St. Ignace. The Country Trail (hiking trail) spans from one side of the UP to the other. So there is literally hiking everywhere in the UP, some better than others, but each unique in it's own right. So if you had some idea of a area, you can get better recommendations of what to see in that area; which can also include other unique things not just hiking suggestions. Most of the waterfalls and all of the best ones are on the west half of the UP. Yes, Tahquamenon falls is really nice, but Bond falls is spectacular.
