Hainan Island is not only sunshine, beach, wave and cactus, but also dormant volcanoes. The volcanic Rocky Mountain volcanic group, which has a history of more than ten thousand years, is one of the few Holocene volcanic eruption dormant mountain groups in China. Nowadays, a multi-functional park has been developed, including volcanic attraction and exploration, appreciation and tracking of volcanic ecology and volcanic culture, health care and vacation of volcanic mineral springs, scientific research and popularization of science. The mountains, rivers, grass and trees here are the marks left by the waste of time. They can walk quietly and relax their body and mind.
