The quality of service in National Parks has received the least attention of all aspects of the leisure and recreation industry. But, in the current era which prizes customer service so highly, this weakness should soon disappear. The Interpretation Service is the key to helping citizens understand what national Parks are all about. Therefore, the quality of the interpretation service in the National Park is almost synonymous with National Park service quality in its entirety. The interpretation process involves many interactions at the service counter. Hence, it is appropriate to apply the Service Blueprint which analyzes the service encounter process of the entire National Park to interpretation activities. The research separates the interpretation activities into HIGH, MEDIUM, and LOW service encounters, and also provides strategies for improvement on the points at which service fails. Lastly, the research makes some suggestions based on the principals of the service blueprint which emphasizes both the visible encounter and the invisible, such as, increasing the automatic computerized interpretive machines, computerizing the administrative paperwork, cooperating with neighborhood schools, adding more attractive interpretation activity design programs, facilitating more interpretative equipment in the field, and setting up an interpretation database.
