A short way up the tributary of the Niyodo River is the Nakatsu Gorge, a natural paradise of boulders and dramatic waterfalls, linked with an easily-walked path and bridges. Interesting birds dive for fish in the translucent pools between the cascades. The clear, blue water churns between the huge boulders that fill the bottom of the gorge. As the path climbs gently upwards, you pass through narrow passages and tunnels between the rocks. Everything sheltered is coated in ancient moss. Here you can experience the turquoise water known as ‘Niyodo blue’.

Towards the top of the gorge, the path is steeper and the sound of falling water becomes more intense. Several bridges lead into a couloir with a spectacular waterfall that pours in numerous streams into pools at different levels. The spray thrown up creates rainbows in the sunbeams that penetrate into the cavernous space. Leaves drifting down from above complete a magical scene.

Staying at the hotel at the entrance to the gorge allows you to enjoy the scenery to the full.
