そらやまゲストハウス|眼下に広がる仁淀ブルー。仁淀川支流の上八川川沿いにあるそらやまゲストハウスは、にこ淵と安居渓谷のほぼ中間に位置するお宿。高知

Yasui valley is one of the best places to see Nyodo Blue , that is where the water is the most blue , the clearest and pristine in kochi. There are several walking paths , one is a gorgeous path along the river all the way to a waterfall , another one takes you to Suishobuchi , a place where the color of the waater is the bluest.
It takes about 30 minutes from the guest house to Yasui valley .
