Our family did the half day Browns Canyon float. We were very nervous because we had very little experience, and during the safety talk it was advised that this was not a simple "booze cruise" float down the river. Once we got on the river and practiced rowing and following the guide's commands, we felt more comfortable. When we got to the rapids, oh my gosh it was awesome!!! The river was really running (class 4 rapids), and we had some near tumbles, but we all made it down the river safely. It was a thrilling adventure for all of us! Highly recommend this tour.
