Cascading or Canyoning (sp) at the waterfalls. I can't swim, so I can not do it, but I'd give anything to be like a fish right now because it looks like so much fun. There are a lot of things that you can do. Here is a small list that I comprised for my group. I will be doing everything but fishing (which I 've never done and would love to try), the helicopter ride, and of course the cascading/white water rafting-anything that requires any swimming skills basically.
