The Water Curtain Cave is located 40 to 47 meters high in the waterfall and is 134 meters long with 6 “windows”, 5 “halls”, 3 springs, and 6 passages. To be near the waterfall is striking already, and to walk in the waterfall is most thrilling and awe-inspiring. No trip to Huangguoshu Waterfall will be complete without a visit to the Water Curtain Cave, as the tourists will not be able to appreciate the magnificence of the waterfall to the full.
There is another wonderful sight when crossing the cave as tourists can watch the rainbows on the Xiniu Pond from different cave “windows”. These rainbows are not only colorful but also change positions. As long as it is sunny, traveler can see them from 9 am to 5 pm, which will change position as he move about. As the ancients say, “the rainbow in the sky is set off by the blue welkin, whereas the rainbow in Xiniu Pond is set off by the snow-white waterfall”, and hence the name “rosy glow on the snow-white waterfall”.
