Follow the woodland pass to the fork in the path (entrance to Kuya-taki Waterfall) which can pass a car, from where the only possible route is that the mountain path (approximately a 1 hour walk from the entrance to Kuya-taki Waterfall).
途中の分岐点（空也滝入口）までは林道が通じ、車も入るが、そこから先は山道を歩く以外の交通手段はない（空也滝入口から徒歩約1時間）。
