Tian Gu · Natural Underground Gallery, a national 4A-level tourist attraction, is acclaimed by numerous domestic geological experts as the first karst cave in the Jiangbei region. It is located in Liuhuyu, Yuandongtou Township, Yishui County, Shandong Province, known as the first ecological township in Yimeng and the hometown of ‘Red Sister’. The scenic area includes the million-year-old ‘Natural Underground Gallery’, the ‘Yiranju’ resort planned and built according to star standards, and the ‘Yimeng First Ecological Valley’, which is mainly composed of a thousand-mu chestnut garden. It is a leisure and entertainment center integrating underground wonders, leisure, residence, catering, conferences, business, science popularization, and fitness.
The ‘Natural Underground Gallery’, sealed for a million years, is located at the foot of Jiuding Lianhua Mountain, with a total length of 6600 meters, and the first phase of development is 1600 meters. Inside the gallery, stalactites are ubiquitous, and stone stalagmites stand tall. The 108 main landscapes are diverse and lifelike. Tianhe, Tianpu, glaciers, jade peaks, stone flowers, stone flags, divine turtles, and wandering dragons are scattered and varied; several stone gates naturally form the mysterious million-year-old scrolls of ‘Northern Scenery’, ‘Cosmic Wonders’, ‘Southern Charm’, and ‘Undersea World’ that have never been shown to the public. ‘Yiranju’ is built on the mountain, with a construction area of over 8000 square meters. Stone houses, thatched cottages, pavilions, and corridors are well arranged, and facilities such as shopping centers, children’s playgrounds, KTV, and camping tents are all available. In the ‘Ecological Valley’, there are cliffs, stone forests, mountain breezes, and pine rhymes, with green water flowing and the fragrance of flowers and birds. With a forest coverage rate of 85%, the area is rich in negative oxygen ions throughout the year, has a pleasant climate, and fresh air, making it an ideal ‘natural oxygen bar’ for people.
