Mt. Iwayu, which has no trees on its summit, is a very beautiful mountain where you can see the rippling Japanese pampas grass that covers the summit in autumn. There are several mountain climbing courses, and the ``Iwaki no Michi,'' which leads leisurely to the observation deck and the summit, offers beautiful cedar forests and thickets of autumn leaves. Additionally, Shikisaikan, a rest area located halfway up the mountain, is a stopping point for hiking trails, so you can gather a variety of information here.
