The old-age valley is located at the confluence of the Qingliu, a source of clear orange mountains, and the upper reaches of the old river and the tributary of the river. The rock tables are steep and steep, and the streams flow. The most beautiful season in the old-age valley should be the time of the autumn maple leaves. The gradient makes the whole valley look beautiful~
along the upper reaches of the river, there are 74 years of collapsed tunnels built 140 years ago. It is a waterfall of Hiroshi Aya, which is called a dream waterfall, and a waterfall of Ozawa, which is called a dream waterfall. The most worthwhile place to visit is the Suwa Waterfall, which is 4 kilometers above the river, with a drop of 30 meters. It is one of the highest waterfalls in Chiba Prefecture. The view of the clear water flowing over the stepped rock is likened to the beauty of the drooping cloth.
The whole valley is not very tired. It is not suitable for family trips. It is also suitable for elderly people to walk, away from the natural scenery of the city.
