The Grand Canyon of the Main Salmon River or, “River of No Return” as it is known; is the perfect juxtaposition of relaxing vacation and thrilling adventure. The numerous class III and occasional class IV rapids are certainly exciting for anyone, but they are also manageable for the first time inflatable kayaker or rafter. The charter plane flight into small-town Idaho add’s a unique sense of adventure. Floating through the continental United States largest wilderness area and second deepest canyon gives an unparalleled feeling of escape and remoteness not attainable in most other places of the country.
