Abstract: As a part of Yandang Mountain World Geopark, Fangshan scenic spot, located in Wenling City, Zhejiang Province, was built on the volcanic strata of Jiuliping formation of the early cretaceous Moshishan group. It is not only a beautiful scenery, but also a profound cultural heritage. However, field investigation shows that there are many hidden dangers of falling rocks in the steep cliffs around Fangshan Mountain and there are also rare hazards caused by falling icicles on the top of steep cliffs in the winter. For example, in the winter of 2017, there was an incident in which ice block from the steep cliff of the scenic spot of Liangyi pavilion smashed the main body of the pavilion and the stone pavement and stone railings on the ground. As Liangyi pavilion is one of the most important scenic spots in Fangshan scenic area, tourists often come here to enjoy the beautiful scenery and sit in the pavilion for a rest. Therefore, the phenomenon of falling rock and /or ice block along the steep cliffs in Liangyi pavilion can seriously threaten the travel safety. In order to ensure travel safety, according to the principle of engineering geology method of mountain tourism planning, the following countermeasures are put forward: under the condition that the viewing value of Liangyi pavilion is basically guaranteed, the route of the scenic spot is adjusted by scientific "avoidance" method, so as to achieve the purpose of eliminating the hidden danger of geological disaster caused by falling rock and /or ice blocks.
