Tucked away in the mountains near the Kurokawa Valley, Handa-Iwa is a serene spot that feels like a local secret. You'll find striking rock formations and a tranquil stream, creating a peaceful atmosphere that changes with the seasons. It's especially beautiful in the fall when the maple trees turn brilliant shades of red and orange. There's no formal car park, so you'll need to find a wide spot on the narrow mountain road and walk a few minutes to the site, but the lack of crowds makes it feel like your own private discovery.
