I signed up for the 2 1/2 hour scenic float. There were five people in our raft plus the guide. We rarely had to paddle. The river was low because it was the end of the season, so a couple times we scraped bottom. The whole trip felt very safe and calm. There were a couple of rapids, but we navigated them easily. I wore a helmet but did not need to. Rafting was a wonderful way to see nature at the glacier area!
