Kawayu Onsen is a unique hot spring where visitors can dig their own hot spring baths in the riverbank. The hot spring water bubbles up directly from beneath the gravel, mixing with the cool river water, allowing guests to create their own perfect soaking spot.

• Access: Kawayu Onsen is accessible by bus from Shingu, Hongu Taisha, and other nearby areas. The nearest major station is Shingu Station, and buses regularly connect visitors to the onsen area.

• Activities: In addition to soaking in the naturally occurring hot spring baths, visitors can enjoy riverside picnics, strolls around the scenic surroundings, and nearby hiking trails within the Kumano Kodo pilgrimage routes.

• Seasonality: The best time to visit Kawayu Onsen is during winter (December ~ February) for the Sennin-buro. During other seasons, visitors can still enjoy the customizable hot spring experience by digging their own spot along the river.

• Accommodation: Several ryokans and guesthouses in the area offer traditional Japanese lodging experiences, with access to the onsen and meals featuring local ingredients.

• No Admission Fees: The natural onsen along the river is free to use, though guests are encouraged to stay at a local ryokan for a more immersive experience.

Tips for Visitors:

• Bring a shovel or rent one locally to dig your hot spring.

• Bathing attire is usually recommended as the onsen is in a public river area.

• In winter, enjoy the communal Sennin-buro, a large outdoor bath made from the river.
