◆ Reach the Summit at Tōtenmon
When hiking the Nyūiwa Gorge trail, setting your goal at the summit’s Tōtenmon (通天門) is highly recommended.
This stunning natural rock formation was created when Nyūiwa (乳岩) was eroded over time, forming a massive archway. The breathtaking panoramic view from this archway allows hikers to gaze at Mount Myōjin (明神山). Interestingly, when viewed from a certain distance, the hole in the rock may not appear as open sky but as something vividly blue.
Reaching Tōtenmon requires climbing a ladder, making the hike somewhat challenging. An even more demanding adventure awaits at the southern "Tōtendō (通天洞)", where hikers must climb ladders through narrow rock passages, providing a thrilling and adrenaline-pumping experience.
To ensure safety, it’s best to visit with both hands free and wear comfortable hiking shoes that offer good grip.
Precautions When Visiting Nyūiwa Gorge
As mentioned earlier, whether you are strolling through Nyūiwa Gorge or hiking along its trails, it is essential to wear comfortable walking shoes and clothing that allow for easy movement. Additionally, be sure to bring appropriate hiking gear and attire to ensure safety during your adventure.
Some areas feature slippery rocks, and there are sections where ladders are required to proceed. It is crucial to have both hands free to navigate these spots safely, as certain high-altitude rock formations pose a slipping hazard. Always be mindful of the risk of sliding from rocky heights.
If you continue along the river toward Myojin Mountain, deeper into Nyūiwa Gorge, you will encounter a breathtaking landscape where caves and waterfalls merge to create a mystical atmosphere. However, this is not a designated hiking trail, and the terrain is particularly slippery. If you plan to explore this area, proceed with extra caution to ensure a safe journey.
Parking and Access to Nyūiwa Gorge
Nyūiwa Gorge is accessible by car, making it a convenient destination for travelers. There is a parking lot available at the trailhead, allowing visitors to park their vehicles close to the entrance. However, due to its convenience, this parking area tends to fill up quickly.
In case the main parking lot is full, an alternative parking space is available. Although it is located a bit farther from the trailhead, using this option ensures a more reliable parking experience.
For those traveling by train, the nearest station is Mikawa-Kawai Station on the JR Iida Line. From there, it takes approximately 40 minutes on foot to reach the gorge. While the walking path is not too steep, it does include some inclines, so staying hydrated, especially during summer visits, is essential.
