If you are interested in white water rafting some the worlds most exotic rivers then look no farther than Bio Bio Expeditions World Wide. I have known Marc Goddard and Laurence Alvarez-Roos the owners of Bio Bio expeditions for almost 30 years and can say without doubt that these are two of the best outfitter/ guides in the world. This is the company that I went rafting and safari traveling with in Africa and kayaking, rafting and horse packing with in Patagonia, Chile. The memories and the friendships you make with your fellow travelers while participating in these adventurous trips will stay with you for a lifetime. Visit their website at http://bbxrafting.com to see some incredible footage of their beautiful destinations. If you would like for me to be your guide on the rivers in either Africa or Patagonia Please mention that you heard about these tours through Mark Kocina.
