The Sumata River is a branch of the Oi River and Sumata Valley is stunning. The bus lumbers through winding mountain roads with breathtaking views before depositing you at the last stop - Sumatakyo Onsen. Once there, there are easy to understand maps that will tell you the way to the onsen, restaurants and hiking trails - all easily accessible.I went in summer, but it's supposed to be even more stunning in fall when the leaves change color. You can hike paths with mountain goats, cross a suspension bridge and wander along the river. When you're finished, head to the outdoor onsen and pay only a couple of hundred yen to relax in natural hot spring water while you look up at the trees and mountains. Makes a great day trip. Be sure to walk with your camera.
