Starting from the Odashirogahara marshland observatory platform, this 8.5 km circuit takes in Lake Sainoko and the Ryuzu Waterfalls. Fine landscapes are on the agenda during the first part, with gigantic Japanese elms and Mongolian oaks. Once you arrive on the pretty Senjugahama Beach, the path's appearance changes. It looks down on Lake Chuzenji and reveals a sublime view behind curtains of azaleas, beeches and maples. To avoid getting a shock, bear in the mind that the rock faces to be climbed are steep in places, and that you may come across a deer, macaque or bear.
