The Payette, Malheur and Owyhee Rivers join the Snake River in what is called the Four Rivers area in and around Ontario, Oregon. Water from these rivers nourishes the highly fertile land, producing a variety of crops that help feed and color the world. The winding Snake River forms the border between Oregon and Idaho and eventually joins the Columbia. Explore this self-guided tour in pieces or take a full day to seek out its many treasures.
