We took our family on a rafting trip down the Sol Duc river during July 2011. The guides were super friendly, knowledgeable, and helpful to get us all outfitted with proper gear to deal with the frigid water. It is definitely worth it to rent the extra clothing (wetsuit or rain gear). The water us 40 degrees and you WILL get wet. Our hands and feet were numb by the end of the trip. The views are gorgeous and you will have opportunities to see water fowl like harlequin duck and American Dippers.
