I'd long heard the saying, "See the Stone Forest above ground, and Jiuxiang underground," and after experiencing it firsthand, I can confirm it's definitely one of the most worthwhile karst caves in China to visit, though it's not an easy trip. The scenic area follows a one-way route. Upon entering, you take a vertical elevator directly down to the canyon, skipping a long steep climb. Then, you take a boat in Yincui Gorge, where the steep cliffs on both sides and the emerald green water create a serene and comfortable atmosphere—a delightful and surprising start to the journey.
After entering the cave, you pass through Jinghun Gorge, the Lion Hall, the Goddess Palace, and then to Shentian and the Twin Waterfalls. The Lion Hall's vast and open underground space is particularly breathtaking; no wonder it was a filming location for old movies. The Twin Waterfalls roar with powerful water, and the spray hits you in the face; standing on the viewing platform, you can truly feel the power of the underground mountains and rivers. The cascading travertine terraces of Shentian, illuminated by lights, are incredibly dreamlike. The entire cave system boasts a high density of scenic features, offering a more natural and wild feel than many caves that rely solely on colored lights.
However, to be honest, the entire route is made up of stone steps, going up and down, with many sections being steep and slippery, and wet everywhere, so be sure to wear non-slip sports shoes. The cave is consistently cool, and there's heavy mist near the waterfall, so it's best to bring a light jacket and a waterproof phone case. If you happen to visit during peak tour periods, the narrow passages can easily cause congestion, and you'll have to queue for photos. The free photos are small; larger sizes require an extra fee. It's recommended to choose a combined ticket for the cable car, otherwise the return climb will be extremely tiring.
Overall, if you enjoy geology, canyons, and caves, this is highly recommended; combining it with a day trip to the Stone Forest is perfect. If you have leg problems, knee injuries, or are simply worried about fatigue, you should consider this carefully. Try to enter the park early to avoid large tour groups for a much better experience.
