Nakatsu Gorge is a gentle 2.3-km trail that essentially anyone can enjoy, regardless of age or hiking experience. It takes you along the upstream area of the crystal blue Niyodo River across adorable little bridges and between towering rock formations that date back over 17,000 years. At the end of the trail awaits the sacred 20-meter-high Uryu-no-Taki waterfall that makes every step of the way worth it
After returning to the start of the hike, stop at Yunomori to fully complete your trip with a dip into the healing, natural hot spring (your body will thank you after all that good exercise!). There is also a lovely restaurant that serves delicious lunch plates featuring local fish and vegetables cooked to perfection
