Most rafting companies, Rock-N-Water included, do not require swimming ability for Class III rafting. On all river trips, you will be outfitted with a PFD, or lifejacket, which will give you lots of extra flotation if you end up in, or chose to be in, the river. Chances are, you will not fall in the water at all on any of our rafting adventures, but if you do, the PFD will take care of keeping you on the surface. We take non-swimmers rafting every year, and it is always a great time.As difficulty increases, some outfitters will require swimming ability for Class IV or V rapids. We WILL take non-swimmers on our Class IV trip on the Middle Fork of the American if they have had a recent Class III rafting experience.
