The trail is an easy walk without any challenging climbs.

Nenokuchi - (20min) - Choshi Otaki - (50min) - Kumoi no Nagare - (30min) - Kumoi no Taki - (30m) - Makado Iwa - (15min) – Ishigedo - (70min) - Yakeyama

The best time to enjoy the area’s verdant greens is from mid-May to mid-June. Gorgeous autumn leaves are at their best from mid to late October. Journey times may be slower due to traffic congestion during these peak seasons. Beat the crowd by starting your trek in the early morning and you will also have the chance to see the fantastic morning dews sparkling in the sunshine filtering through the foliage.
