This is not an excursion to take in October if you don't like the freezing cold. It's a really nice tour. The guy who was narrating the tour was sometimes impossible to hear over the boat's engine even on the loud speaker. He would take questions from passengers and then not repeat the questions for everyone to hear. He would go ahead and answer the question which was confusion to those that didn't hear it.
This was a great ride for those that weren't scared to death of it. The crazy little driver took this little speed boat into rapids and flung the boat around all wild and such. I was much too scared but everyone else enjoyed it immensely.
