Rather than take the guided tour with my family of 10, I rented a pontoon boat here and let my son-in-law pilot it. We spent more than two hours on the lake, with the grownups mostly enjoying the spectacular views and the kids jumping off into the lake over and over again. The boat accommodated our family nicely--very comfortable and clean, with part of it covered. An employee made sure that each child was fitted with an appropriate life jacket, and another employee provided instructions about using the boat. We paid a flat fee for each of the two hours and only a pro-rated fee for the additional 15 minutes. Highly recommended for families with swimmers.
