Zhangjiajie National Forest Park, located in the Hunan province of China, is renowned for its breathtaking landscape of towering sandstone pillars and lush forests. Established in 1982, it was China's first national forest park and was recognized as a UNESCO World Heritage Site in 1992. The park's unique geological formations, including the pillar-like structures that inspired the floating mountains in the movie "Avatar", are the result of thousands of years of erosion. Visitors can explore this natural wonder and experience its beauty through activities like hiking and photography.
