Oyasu Ravine 小安峡
A lush valley full of onsen, year-round recreation and a Bathtub of Hell
Located at the entrance to Kurikoma Quasi-National Park, Oyasu Ravine has V-shaped cliffs that are four kilometers long and 60 meters high, creating a dramatic sight.
Walk down the stairs to the bottom of the valley where you will see a hot river, enveloped by lush trees and small waterfalls. Heated by natural thermal currents, the river creates clouds of steam.
