The tour was great for the most part. The tour bus arrived on time for pick up and the tour guide was entertaining and funny. We actually got a tour inside the dam and got to see what goes on underneath it. There was a museum which shows how the dam was created. The tour was very informative and interesting. My favorite was walking across the dam. I have a fear of heights, so looking down was a problem! Part of the tour that I went on included a visit to a nearby chocolate factory. The factory was ok, there wasn't any chocolate being made that day, so I was kinda bummed. I did get a free sample though. But I felt the factory tour wasn't necessary. I would rather just visit the dam and nothing else. But I got a package that include other tours beside the dam. So if you want to visit the dam, either go on your own or try to get a tour where you just visit the dam.
