The Futaleufu River, the name of which means “big big river,” is known in whitewater circles as one of the most exciting and challenging rivers in the world, according to Expediciones Chile. “It is an exhilarating whitewater power storm of turquoise champagne like water.” The Class 4/5 Terminator section, which some experienced kayakers call the most difficult commercially run rapid in the world, is 6 miles and it takes about 3 hours.
