I am hoping to take my son on a hike and float trip in 2 weeks. Maybe like a 15 mile hike, then float back to the start, or near it at least. I don't own any rivercraft, but have been rafting and kayaking on class III/IV. My son is 10, and is a strong swimmer, but I don't want to take him on anything aggressive. Does any know of a good hike that would take me to a put-in where I could rent a raft or canoe that I could take back to the start and would be picked up by the place I rented it from? I would prefer places in Wisconsin, UP, or Indiana, but I would take suggestions in Missouri and Illinois. I posted in the r/rafting community, but am also posting here in hopes of receiving good hiking recs that also have a float component. Thank You
