I have taken mine on rivers, lakes, and under the Golden Gate bridge on the north side to where the old cannon bunkers are. It can navigate rivers, but because it is a sit on top, you really want to be careful on what river you want to take it on. Any river that is class 2-3 I would defiantly want to scout it out on a raft first. It is very maneuverable but because the only thing holding you in is you, one wrong step and you can be on a you tube video.So I would say for rivers that are more float style with mild rapids and shallows you would be safe, just get very comfortable with how the boat handles and then go with your experience level. Happy Paddling
