Stone Forest Introduction: The Bamboo Sea Stone Forest is located in Yiniutang, the core scenic spot of Bamboo Sea. It is the only white marble stone forest in the country, stretching for nearly 160,000 acres, with rugged rocks and unique flavor. Among them, there are more than 20 species of bamboos, mainly Nanzhu. It is the only scenic spot in southern Hunan dominated by bamboo sea. Bamboos, stones, caves, and springs complement each other, especially the natural stone forest tunnel, which is particularly interesting.
