The guided tour is a total rip off. We didn't even get to row the boat, it cost literally twice as much, and we didn't even get wet. It was a lame 1.5 hours, thought the guide was nice, all we got to do was sit on a boat for an hour and a half and chat with the guide, because the river sure wasn't interesting enough to be considered rafting. It wasn't even the promised two hours long, not that it would have been any more enjoyable had it been the full length. Overall, I feel cheated and gipped.
