Kamikura-jinja & Gotobiki-iwa — Shingu; morning, ~1 hour. Climb the steep stone staircase to this dramatic sacred rock and enjoy panoramic views over the city and coast.
Kumano Hayatama Taisha — Shingu; morning, ~1 hour. Visit one of the Kumano Sanzan’s grandest shrines, known for its vermilion buildings and ancient sacred tree.
Shingu Castle Ruins — Shingu; late morning, ~45 minutes. Walk the hilltop remains for broad views across Shingu and the Kumano River.
Kumano-gawa River Boat Centre — Shingu; midday, ~30 minutes. Have lunch nearby at a local seafood or Japanese set-meal restaurant, budgeting approximately ¥1,000–¥2,000 per person, before traveling inland toward Hongu.
Kumano Hongu Taisha & Oyunohara — Hongu; afternoon, ~2 hours. Explore the pilgrimage’s principal shrine and walk to Oyunohara, marked by Japan’s enormous torii gate.

Start at Kamikura-jinja & Gotobiki-iwa, reached by a steep climb of roughly 538 uneven stone steps from the trail entrance. Allow about an hour, wear proper shoes, and avoid rushing in August heat; the huge sacred rock and views over Shingu and the Pacific are worth the effort. Descend carefully, then walk around 20 minutes to Kumano Hayatama Taisha, one of the Kumano Sanzan, where the vermilion shrine buildings and enormous sacred nagi tree make a calmer contrast to the climb. The shrine grounds are generally accessible from early morning, with no admission fee; bring water, as shade is limited on parts of the route.
Continue on foot or by a short taxi ride to Shingu Castle Ruins for about 45 minutes. The hilltop is a pleasant place to pause, with wide views over the Kumano River and town, though little of the original castle remains. For lunch, stop near the Kumano-gawa River Boat Centre—even if you are not taking a boat trip—at a local seafood or Japanese set-meal restaurant in central Shingu. Budget ¥1,000–¥2,000 per person, and allow time to check bus departures before leaving; inland services are limited and less frequent than city buses.
Take the bus from Shingu toward Hongu, allowing roughly 60–90 minutes depending on the service, and get off for Kumano Hongu Taisha. Climb the shrine’s broad staircase and spend time in the quiet forested grounds before walking to Oyunohara, around 10–15 minutes away, where Japan’s enormous torii marks the former shrine site. The combined visit works well in about two hours. From Hongu, continue by local bus to Yunomine Onsen; check the current timetable at the bus terminal or tourist office, since late-afternoon departures are widely spaced. At Yunomine Onsen, collect a numbered time slot for the UNESCO-listed Tsuboyu if available—bathing is brief and availability is limited—and use the public Yuzutsu hot spring to boil an egg, buying one locally. Aim to leave by around 16:30–17:00 for Kawayu Onsen, where your ryokan can usually arrange pickup or explain the short bus connection. After check-in, change into comfortable clothes and dig a shallow bath in the riverbank gravel; the water is hot, so mix it with river water and test the temperature frequently. Summer evenings are ideal for this riverside ritual, but follow local bathing rules and stop if the river rises after rain.
