Canyon great, River Cruise so-so

The tour was great and the guide had a lot of knowledge about Kauai. I was pleased to see how much of the south shore was covered in the tour. I wish they would have gone to the two other lookout points on the canyon before turning back but otherwise the stops were great. The river cruise was a little disappointing and the fern grotto, even though beautiful, wasn't worth the time spent getting there. If I had to do it again, I would just do the tour.
