This was an optional excursion on our recent bus tour, and we were not planning to take part. A little persuasion from some newly made friends made us change our minds and my wife and I are eternally grateful. It was one of the most truly relaxing experiences I have ever had (once I was able to get into the raft, which I did quite clumsily) Unfortunately, we missed a lot of the wildlife (just a matter of timing, I suppose), but we did see a dozen or so bald eagles. It was memorable regardless. Don't worry about getting wet on this ride, I only got lightly spritzed on occasion. The guides are extremely knowledgeable and gladly answer any and all questions. Do not pass this up if you get the opportunity.
