Spent the day at Ohtama Walking Trail in Okutama, a mostly flat 3.5-hour walk along the Okutama River with diverse forest, river, and residential scenery. Passing by quaint houses, a waterfall, and cross bridges that overlook the river. The route also includes a tunnel and a dam. It connects Kori Station and Okutama Station on the Ome Line. You can start from either end. It's beautiful year-round, but probably best to go during the Fall season when the ravine area is covered with yellow, orange, and red colors.
