1. Introduction Tentsu (heaven pond) area is the mid point of southern-trans-island high way, as well as the very important landmark. This alpine lake plays a crucial ecological role. But due to religious reasons, the locals are inclined to set lives free back to the wild near the lake area; such acts as a result has profoundly negative ecological affects in the area. The Kung-shan historic trail through Tentsu area was built in the Japanese colonial time. Recently Chung-jie-kung historic trail has been remodeled in order to attract the tourists. But the natural resources and sceneries alongside should be more detailed acknowledged and put on more systematic display. 2. Methods and Protocol To coordinate the purpose of research, Tentsu recreation area and Chung-jie-kung historic trail have been decided to be the research area. The research starts with literature review and field survey. The literature review includes: literature and map at the governor house of Taiwan during Japanese colonial time, the contemporary Japanese literature of Chung-jie-kung historic trail, activities of indigenous people, records or mountain climbing and photographs of various time period. All these can be the adapted as the contents of explanation. The activities of field research include on-site studies of the routes in question, including road conditions and the local landscape, and the studies of the native vegetation and existing leisure and tourism facilities. The result of the initial research will be collated with opinions from subject matter experts and results from tourist focus groups studies for further analysis. The outcome analysis will be used in the formulation of an appropriate plan to provide the necessary infrastructures for tourism information provision for the general public. This plan, together with other recommendations to improve local leisure infrastructures, will be submitted to the relevant government agencies for future reference. 3. Findings and Results Interpretation system plays an important role in information provision for the visitors. At the same time, it is also the first point of contact in most scenarios. The common issues that exist among these systems in Chung-jie-kung historic trail include: too many different forms of signage, the material of signage not durable, too many signs at the same spot, and unclear printing of signage… etc. All these bring to the public unclear messages and confusion. In terms of signage materials, not only we need to consider their overall fit to the surrounding environment, it is also important to take durability, maintainability and potential for future upgrade into account. Furthermore, the use of the signage structures should be carefully planned to minimize any negative impacts to the environment, and ensure they do not visually overwhelm their target audience. 4. Discussion Yu-shan national park had printed Chung-jie-kung historic trail tourism pamphlets. The contents of the booklet are detailed and easy to understand but the pamphlets are not easy to obtain. The contents should be categorized into three parts – Plants, wildlife, Culture and History. The cultural and historic activities, including Bu-non tribe acted against Japan, build historical trail and mountain climbing, are more introduced at the interpretation pavilion of Chung-jie-kung historic station, but not at the May-shan visitor center. The public facilities, including：acceess for disable toilet design at Tentsu recreation area, entrance image of Chung-jie-kung historic trail, historic site experience area plan, and extention and upgrade of camping site, should all be remodeled.
