Amnicon

I talked to the rangers at Amnicon Falls this summer about the run. They said they didn't want people putting in from the Park, but you could start further up. According to the ranger I talked to, everything below the high water mark is public, so it would be possible to scout the drops - some of which looked quite nice. However, they were understandably concerned with liability and the possibility that this would encourage unskilled spectator-type people to attempt this run, as it is a popular park. While that ranger did not say it was forbidden or illegal, I think it would be a good idea to discuss your plans with them beforehand.
