This is the same indoor gym as described before under the Zhejiang Technical Sports College. However, as of April 2013 it has been updated with a new cave/bouldering section as well as small climbing shop. There is a large wall with 20+ routes including 10+ lead routes.
As of 4/2013, there is a small fee for using the gym: 50 RMB for a single use, 35 RMB for students. There are shoes and harnesses available for rent. The wall is staffed by several very friendly climbers who will belay you. They will also serve as bouldering "coaches" and will create problems for you on the fly. They use a Western rating system (V0-6 and 5.8-5.12) which is relatively accurate.
