The scenery in the valley is absolutely stunning, and the stream is so clear you can see right to the bottom. It's like a real-life landscape painting.
You don't have to walk the whole trail to enjoy the beautiful scenery—you can take the bus and do it in sections. There are lots of small waterfalls and photo spots along the way, like Ashura Stream and Choshi Otaki, which are must-see spots.
The best time to visit is June to August when the flowers are in full bloom and the weather is just right. It's not just the flowers—the scenery around here is gorgeous too. Perfect spot for landscape photos.
