Hiking along the Bride Route

Despite its low elevation, this 5-hour up and down route is best attempted by fit, experienced hikers, as there are no escape routes along the way. It’s recommended to do it in a clockwise direction, starting with the “hanayome” or bride route (花嫁コース), continuing with the “hanamuko” or bridegroom route (花婿コース), and ending with the “kurotaki” or black waterfall Route (黒滝コース) which passes by Kurotaki waterfall.
