The purpose of this study is to measure the service quality at the campsite by utilizing the Importance-Performance Analysis (IPA) to identify factors that need to be improved from the users’ perspective. 260 questionnaires were distributed. Factor analysis was conducted, and the service quality of campsites is divided into four aspects: "safety", " tangible environment", "service convenience" and "interactive quality". The quantitative analysis of the questionnaires was conducted through independent sample t-test, single factor analysis of variance, correlation analysis, regression analysis, and importance-performance analysis in this study. The results are as follows: (1) the safety of campsites is the most important element for campers, and more men than women pay attention to this factor, (2) the tangible environment of campsites is the most important element that needs to be improved, especially in terms of clean water, good sanitary facilities, and sanitation, (3) the interactive quality of campsites is less valued by campers, and (4) convenience is a service quality that campers think is over-provided.
