One of Kansai's best hikes, the Yagyu Kaido follows the old samurai trail from the village of Yagyu in the pristine Nara countryside through the Kasugayama Primeval Forest into Nara. The highlights trail skips Yagyu and instead you start from the beautiful temple of Enjo-ji, about half way along the trail.
