The area of Hangzhou is also famous for its grottoes. One of the biggest, and most beautiful, is the Jin Xiu Fen Shui Grotto. This is a huge grotto, nicely illuminated. The visit to the grotto will take you one hour. You will have to walk a lot, and climb some steep steps. In some parts of the grotto, water pours through the ceiling and falls onto visitors' heads. Bringing a cap is recommended. Inside the cave there is a small train, you will take it to get out of the grotto at a respectable speed. Nice visit.
