Yes, bathing is permitted in the natural pools at the base of the waterfall. However, swimsuits are required as this is a public bathing area. The best bathing season is from early July to mid-September when water temperatures and flow rates are most comfortable. Outside this period, the water can be too cold or the flow too strong for safe bathing.
There is no direct public transportation to the waterfall. The most convenient option is driving from Yuzawa Station, which takes approximately 45 minutes covering 30 kilometers to reach the Banzawa Takamatsu area where free parking is available. From the parking lot, it's a 15-minute walk to the falls. Alternatively, you can take a local bus from Yuzawa City to Doroyu Onsen and hike the remaining 3 kilometers, or book a shuttle service through Yuzawa tourism offices.
Kawarage Oyutaki is located near Kawarage Jigoku, one of Japan's three major sacred mountains. Kawarage Jigoku was founded by Priest Gesso in 807 and features a volcanic landscape with gray-white lava rocks, steam vents, and a strong sulfur smell that gives it the name "Jigoku" (hell). The thermal water that feeds the waterfall originates from this volcanic activity, flowing approximately 1 kilometer downstream before cascading over the falls. Doroyu Onsen village, with 1,200 years of history, is located about 2 kilometers from Kawarage Jigoku.
The water temperature varies depending on how much cold river water mixes with the thermal spring, so some areas may be hotter or cooler than others. The water is acidic due to its volcanic origin, which can occasionally cause minor skin irritation for sensitive individuals. Always test the water temperature before entering and be cautious of slippery rocks around the waterfall. The 15-minute walk from parking requires basic hiking ability, and appropriate footwear is recommended for the trail.
