Away from the crowds and tour buses, the spectacular Oku Iya Ni-jū Kazura-bashi are two secluded vine bridges hanging side by side high over the river. Cross one and come back over the other. A self-propelled, two-seated wooden cable-cart is another fun way to cross the river; there's a small public camping area on the other side. There are also a couple of spots where you can get down to the river and enjoy the serenity.
