Mount Lushan Geopark in Jiangxi Province, Wudalianchi Geopark in Heilongjiang Province and the iconic Zhangjiajie Geopark in Hunan Province received warnings on January 9 for failing to offer visitors appropriate geographical information, state-run Xinhua news agency reported.
All three geoparks have been given time until 2014 to improve their services and pass comprehensive evaluations by the Global Geopark Network.
Several tourists at the Zhangjiajie Geopark contacted by state-run Global Times complained that some local tour guides are not very knowledgeable.
Zhang Jianguo, director of the Zhangjiajie Geopark's land and resources office said that the local government would improve the facilities by launching a geology museum.
"If they want to stay on the list, Zhangjiajie and other geoparks should think about more than just making money," Fang Shiming, a professor of Wuhan-based China University of Geosciences said.
China has about 45 locations including the Great Wall of China in the UNESCO heritage list.
